Mastering Brake Repair for Safer Journeys Ahead

February 21, 2024 by Denver Express Car Care

In the whirlwind of life’s demands, Aileen is a mom, a professional, and a woman perpetually on the move. With two kids in tow and a job that navigates her through the city’s hustle, Aileen’s vehicle isn’t just a means of transport; it’s the unsung hero of her daily adventures. 

A typical morning includes coffee in hand, a to-do list in mind, and Aileen ready to conquer the week. Yet, amidst the organized chaos, a sudden interruption: a subtle sputter and the ominous glow of a dashboard light. Panic ensues as Aileen realizes her trusted companion, her vehicle, is hinting at a potential hiccup, threatening to derail her precisely planned schedule.

If you’ve ever felt the dread of unexpected car troubles, you’re not alone. Aileen’s story resonates with countless individuals who rely on their vehicles to keep up with life’s fast pace. 

What if your brakes squeal? What if you know you need brake repair? 

What next? 

Pay attention to what’s happening with your car

The worst thing you can do is ignore your vehicle. 

Mastering Brake Repair for Safer Journeys Ahead

We get busy. We have lots of things on our minds. But cars slowly degrade until they reach a point where they need a little care. The sooner you catch it, the easier the repair, the lower the potential cost will be. 

For a mom like Aileen, that’s important. She lives on a budget – why pay more for repairs if she can maintain her car and avoid bigger problems? 

It’s also a matter of safety. She carries her kids to activities each day. She often has other kids in her car. Safety matters. 

Which is why it’s important to pay attention. 

Ever noticed a high-pitched squeal or a grinding noise when you hit the brakes? It’s like your car is trying to tell you something. Usually, these sounds are red flags indicating worn-out brake pads or, in more serious cases, damaged rotors. Don’t let these audible alarms go unnoticed – they’re your vehicle’s way of saying, “Hey, I need some attention!”

Or maybe you notice the way your brake pedal responds. If it suddenly feels spongy, requires more pressure, or, on the flip side, becomes overly sensitive, it’s time to pay attention. Changes in pedal feel might suggest issues with your brake fluid or a potential brake system malfunction. Ignoring these signs could compromise your ability to stop safely.

Imagine hitting the brakes, and there’s an unexpected shimmy or vibration steering your car. This might be an indication of warped brake rotors. While it might not feel like an urgent concern, letting this issue linger can lead to uneven brake pad wear and, ultimately, a compromised braking performance.

Simple things to do for brake repair …

Today’s cars are sophisticated vehicles. While each system is put together with dozens of parts, technology is what holds it all together. Vehicles are as much technology-driven as they are mechanically inclined. 

It’s why you should bring your vehicle to a qualified, reputable mechanic at the first sign of trouble. 

Still, there are things you can do – so you’re not running into an auto repair shop at every sound. 

Start with a visual check. Even if you know very little about car maintenance, you can notice certain problems. Is there fluid underneath your car when you drive away? Where is it located? What color is it? You can even peek through the spokes of your wheels to get a glimpse of your brake components. Does one wheel look differently than another? 

Remember those sounds we talked about? Take a moment in a quiet space to listen as you lightly tap the brakes. Squeals, squeaks, or grinding noises might signal wear and tear. If you hear something unusual, it’s worth scheduling a check-up.

Sit in your car, start the engine, and gently press the brake pedal. It should feel firm, not mushy. If it feels soft or requires excessive effort, it’s worth investigating. Also, pay attention to any vibrations or pulsations, as these could hint at rotor issues.

Your car’s brake fluid is crucial for optimal brake performance. Pop the hood, locate the brake fluid reservoir, and check the level. If it’s low, it might indicate a leak or wear in the brake system. Ensure the fluid is clear and doesn’t look murky or discolored. And if there’s a leak, it’s time to bring your vehicle in for repair. 

Believe it or not, tire rotation plays a role in brake health. Regularly rotating your tires ensures even wear on brake pads and extends their lifespan. Plus, it contributes to a smoother ride. And it gives a trusted mechanic a chance to ensure other items aren’t in disrepair. 

Ensuring your car’s safety as you go …

In the ebb and flow of city traffic, your brakes become your constant companion. Frequent stops and accelerations take a toll on brake pads. Well-maintained brakes not only ensure a smoother driving experience but also contribute to fuel efficiency by minimizing unnecessary friction.

Of course, life isn’t all about normalcy. Your brakes need to be ready for the unexpected, too. 

Imagine you’re rushing to pick up the kids from school, and a car unexpectedly swerves in front of you. Your ability to bring your vehicle to a swift and controlled stop depends on the efficiency of your brakes. Regular maintenance ensures they’re up to the task when split-second decisions are crucial.

Sometimes, you can’t see what’s in your path. Whether it’s a sudden pothole or an unexpected obstacle in the road, well-maintained brakes provide the responsiveness needed to navigate unforeseen challenges. It’s your first line of defense against the unpredictable nature of daily driving.

And it’s not just about you. Your car is more than a mode of transportation; it’s a shield for you and your loved ones. Well-maintained brakes are a fundamental component of your vehicle’s safety system. Investing time in their care is an investment in the safety of everyone on board.

So, let me ask you a question: Are you an Aileen? Do you drive all over town, rarely thinking of your car’s brakes?

Maybe it’s time for a change. Awareness is key. It sets the stage for a better driving experience overall. And ensuring your safety no matter where the road takes you. 

Can we assist you with your brake repair?

Brake Maintenance Tips When Mountain Driving is a Part of Your Life

January 24, 2024 by Denver Express Car Care

Need to get from Denver to Evergreen? On a good day, you can be there in under an hour, depending on where you’re coming from and going to. Many people do this drive every day to and from work. 

Every time you make this drive, the elevation changes by 2700 feet. That’s just over 51 percent grade. If you’ve made the trip, you know your engine hums as it climbs. Your brakes get pushed to the limits as you come back down. 

Are your brakes in good operating condition?  

If not, the drive can be a harrowing experience. 

Few drivers would argue the importance of a good braking system. Depending on your drive here along the Front Range, it’s literally a life-or-death situation. That’s why we prepare for it – ever seen braking ramps along the side of the highway? 

But as a driver, you can prevent braking problems long before you notice them. With a few brake maintenance tips in mind, your brakes will always be in good condition, and be able to take on whatever your daily plans can dish out. 

Why brake maintenance is even more important with mountain driving

Brake maintenance is always crucial, even more so when mountain driving is a regular part of your life. The challenging terrain and varying elevations pose unique demands on your vehicle’s braking system. 

Brake Maintenance Tips When Mountain Driving is a Part of Your Life
  • You’re constantly in motion – steep ascents and descents. Descending long and winding slopes can generate significant heat in the braking system, leading to brake fade or reduced effectiveness. Regular maintenance helps ensure your brakes can handle the stress of elevation changes.
  • Continuous braking while navigating downhill stretches can accelerate brake pad and rotor wear. The extended use can lead to overheating, compromising the overall performance of the braking system. Routine maintenance helps identify and address wear issues before they become more severe.
  • Mountain driving often involves prolonged downhill descents, requiring sustained use of the brakes to control speed. This places additional strain on the braking components, making it crucial to have well-maintained brakes to ensure reliable performance and prevent overheating.
  • Brake fade occurs when the braking system loses effectiveness due to overheating. This can be particularly hazardous in mountainous terrain where precise vehicle control is essential. Regular brake inspections and maintenance help mitigate the risk of brake fade and ensure optimal braking performance.
  • Mountain driving can expose your vehicle to varying temperatures and environmental conditions. Regular brake maintenance includes checking and maintaining the integrity of brake fluid. Proper fluid levels and quality are essential for consistent braking performance, especially in challenging terrains.

Top brake issues to watch for

If mountain driving is a regular part of your life, staying vigilant about your vehicle’s braking system is essential. You have the possibility of facing more brake issues, sooner. Things to watch for include:

Worn out brake pads

Watch out for squeaking or grinding noises during braking, reduced braking responsiveness. Worn brake pads compromise the effectiveness of your braking system, especially during downhill descents where brakes are frequently used.

Warped rotors

You may notice vibrations or pulsations felt through the brake pedal during braking. Warped rotors can lead to uneven braking, reducing your ability to maintain control, particularly in demanding mountainous conditions.

Brake fluid leaks

Puddles or wet spots beneath the vehicle may be a sign of a gradual decrease in brake fluid levels. Brake fluid is essential for optimal brake performance. Any leaks can compromise the system, leading to a potential loss of braking power.

Smoking brakes

Visible smoke or a burning smell from the wheels is never a good thing. Overheated brakes can result from prolonged downhill descents. Smoking brakes indicate a critical temperature level, and immediate action is necessary to prevent brake fade and potential failure.

Never ignore brake warning lights

Modern vehicles are equipped with brake warning lights that illuminate when an issue is detected. Ignoring these warnings can lead to severe consequences. Always address brake warning lights promptly by seeking professional inspection and maintenance.

Regularly checking for these brake issues is essential for your safety, especially when navigating the challenging terrain of mountain roads. If you notice any signs of brake problems or experience unusual braking behavior, it’s crucial to address them promptly to maintain optimal braking performance and ensure a secure driving experience as you move in and out of the hills. 

Practical brake maintenance tips to help you address and prevent these issues

Maintaining a healthy braking system is key to ensuring your safety when driving anywhere in the city, including in and out of the Rocky Mountains. Your maintenance should include:

Regular brake inspections

Schedule routine brake inspections, especially before embarking on extended mountain journeys. Regular inspections help identify early signs of brake wear, ensuring timely replacement of brake pads and detection of other potential issues.

Monitor brake pad thickness

Monitor the thickness of your brake pads regularly. The good news is brake pads are built with an internal warning system, and will squeal as they approach end-of-life. Worn-out brake pads can compromise braking efficiency, particularly during downhill descents. Replace pads if they are approaching the minimum thickness.

Rotor inspection

Inspect brake rotors for signs of warping or uneven wear. Warped rotors can lead to vibrations and reduced braking performance. Address any rotor issues promptly to maintain optimal braking.

Brake fluid checks

Regularly check brake fluid levels and quality. Brake fluid is crucial for proper brake function. Low levels or degraded fluid can lead to decreased braking efficiency. Top up or replace brake fluid as needed.

Address brake fluid leaks immediately

If you notice brake fluid leaks, seek professional assistance immediately. Brake fluid leaks can compromise the entire braking system. Prompt repairs prevent potential brake failure.

Avoid prolonged braking

Use engine braking and downshifting on downhill stretches to reduce reliance on brakes. Prolonged braking during descents generates excessive heat, potentially leading to brake fade. Alternate braking techniques help mitigate heat buildup.

Cooling periods

Allow brakes to cool down during long drives by pulling over and taking breaks. Cooling periods prevent brakes from overheating, reducing the risk of issues like smoking brakes.

Heed brake warning lights

Address brake warning lights promptly by seeking professional inspection. Ignoring warning lights can lead to more severe issues. Early detection and intervention are crucial for brake system health.

By incorporating these practical brake maintenance tips into your routine, you can enhance the reliability and longevity of your braking system, ensuring a safer driving experience through whatever you face during your daily commute.

Brake Mastery: Understanding the Anatomy of a Smooth and Safe Stop

January 3, 2024 by Denver Express Car Care

Accidents are never planned. Instead, you’re out and about, accomplishing your daily task list when – wham – you’re now part of a statistic. 

The thing about accidents is most are preventable. Most are driver errors. Statistics show that over 50 percent of all accidents in the US are caused by aggressive drivers. Rear-end collisions are the most common, with tailgating contributing to more than one-third of all crashes. 

Slowing down and becoming an offensive driver can increase your odds of living accident-free. The other is regular maintenance – well-performing brakes ensure your safety.

Brakes are one of the most essential safety systems on your vehicle. Well-functioning brakes ensure your safety no matter where your drive takes you. It’s also a skill. Do you understand how to brake safely?

Understanding how a car’s brake system should work

The brakes play a fundamental role in bringing your vehicle to a halt, and a well-functioning brake system is essential for your safety and the safety of others on the road. Let’s break down the basics of how a car’s brake system should work in simple terms.

Brake Mastery: Understanding the Anatomy of a Smooth and Safe Stop

The Brake Components

At its core, a car’s brake system consists of several key components. The main players are the brake pedal, brake fluid, brake pads, and brake rotors (also known as brake discs). These components work together seamlessly to slow down and stop your vehicle when needed.

Initiating the Stop

When you press the brake pedal with your foot, you’re initiating a series of actions that lead to your car slowing down or coming to a stop. This action triggers a hydraulic system that sends brake fluid to the brake calipers.

Hydraulic Power

Brake fluid is a hydraulic fluid that transfers the force from your foot on the brake pedal to the brake calipers near each wheel. This hydraulic force ultimately squeezes the brake pads against the brake rotors.

Friction and Slowing Down

The brake pads, positioned on either side of the brake rotor, are designed to create friction when pressed against the rotating rotor. This friction slows down the wheel and, consequently, the entire vehicle. It’s like a controlled version of rubbing your palms together to create heat.

Smooth and Safe Stop

The key to a smooth and safe stop lies in the balance of these components. The brake system should respond predictably and consistently, allowing you to slow down or stop without surprises. If everything is working as it should, you’ll experience a controlled deceleration, bringing your car to a halt without jerks or unexpected jolts.

What happens when your brake system is no longer working optimally

Brakes come with a suggested lifespan, but it’s only suggested. Every system wears down at its own pace, depending on your unique situation. 

  • How much you drive
  • Where you park your car
  • Climate
  • Weather conditions
  • Driving conditions
  • Maintenance routines

All of it matters. 

Even the most reliable brake systems can experience wear and tear over time. The key is recognizing the signs of a brake system no longer working optimally. Let’s explore common indicators that it’s time to give your brakes some attention:

Screeching or Squealing Noises

One of the earliest warning signs of brake trouble is often an audible one. If you start to hear a high-pitched screech or squeal when applying the brakes, it could be an indication that the brake pads are wearing thin. The noise is typically produced by a small metal shim called an indicator, designed to alert you when the pads are nearing the end of their lifespan.

Grinding Sensation

A grinding sensation when braking is a red flag. This could mean the brake pads have worn down completely, and the metal backing is now grinding against the brake rotor. Driving with this issue can cause significant damage to the rotors, leading to more extensive and costly repairs.

Soft or Spongy Brake Pedal

A healthy brake pedal should feel firm and responsive. If you notice a soft or spongy sensation when you press the brake pedal, it may indicate air or moisture in the brake fluid, a potential leak, or a problem with the master cylinder. In any case, it’s essential to address this issue promptly for optimal braking performance.

Vibrations or Pulsations

If you feel vibrations or pulsations through the brake pedal or steering wheel when braking, it could be a sign of warped brake rotors. Warping can occur due to overheating during prolonged or aggressive braking. This issue not only affects the effectiveness of your brakes but also compromises the smoothness of your stops.

Uneven Braking

Pay attention to uneven braking, where your car pulls to one side when you apply the brakes. This may suggest uneven wear on the brake pads or issues with the brake calipers. Properly functioning brakes should provide consistent stopping power without any noticeable deviation.

Dashboard Warning Lights

Modern vehicles are equipped with electronic systems that monitor various aspects, including the brake system. If you see a warning light on your dashboard that resembles a circle with an exclamation mark or the word “BRAKE,” it’s a signal from your car’s computer that there may be an issue with the brake system. Ignoring such warnings can lead to more severe problems over time.

Burning Smell

If you detect a burning smell, especially after heavy or prolonged braking, it could indicate overheating brakes. Overheating can compromise the efficiency of the brake system and may result in brake fade, where the brakes become less responsive.

Recognizing these signs promptly and addressing them with professional inspection and maintenance can prevent further damage and ensure the continued effectiveness of your brake system. 

Proactive measures you can take to maintain your brake system and promote longevity

While recognizing warning signs can help you get your vehicle in for maintenance before you face road hazards, there are other things you can do to maintain a healthy brake system. Here are some proactive measures you can take to ensure the longevity and optimal performance of your car’s brake system:

Regular Inspections

Schedule regular brake inspections, ideally during routine maintenance visits or whenever you notice any unusual signs. Professional inspections can identify potential issues before they escalate into more significant problems.

Check Brake Fluid Levels

Brake fluid plays a crucial role in the hydraulic system that enables your brakes to function. Periodically check the brake fluid levels and top up if necessary. Consult your vehicle’s manual for the recommended type of brake fluid and follow any guidelines for proper fluid maintenance.

Replace Brake Fluid

Over time, brake fluid can absorb moisture, compromising its effectiveness. Consider replacing the brake fluid as recommended by your vehicle’s manufacturer. This helps maintain the hydraulic integrity of the system, preventing issues like a soft or spongy brake pedal.

Monitor Brake Pad Thickness

Keep an eye on the thickness of your brake pads. Most brake pads have wear indicators that become visible as the pads wear down. If the pads are nearing the end of their lifespan, have them replaced promptly to avoid damage to other brake components.

Address Brake Fluid Leaks

Any signs of brake fluid leaks should be addressed immediately. Brake fluid leaks not only compromise braking performance but can also lead to more extensive and costly repairs. If you notice a puddle or stains beneath your car near the wheels, have a professional inspect and repair the issue.

Avoid Aggressive Driving

Prolonged or aggressive braking generates excessive heat, which can accelerate wear on brake components. Try to drive in a manner that minimizes the need for sudden, heavy braking. This helps preserve your brake system and contributes to better fuel efficiency.

Rotate Tires Regularly

Uneven tire wear can impact the effectiveness of your brakes. Regularly rotating your tires helps ensure even wear on both the tires and brake pads. This simple maintenance task contributes to a more balanced and reliable braking system.

Follow Manufacturer Recommendations

Adhere to the maintenance schedule and recommendations outlined in your vehicle’s manual. Manufacturers provide guidelines for brake system maintenance based on the specific make and model of your car. Following these recommendations can extend the life of your brake components.

Brake System Flush

Consider periodic brake system flushes, especially if recommended by your vehicle’s manufacturer. A brake system flush involves replacing old brake fluid with fresh fluid, helping remove any contaminants that may have accumulated over time.

DIY Checks

In addition to professional inspections, perform basic DIY checks, such as visually inspecting brake components for signs of wear, and listening for any unusual sounds when braking. Early detection of issues allows for timely intervention.

Remember, a well-maintained brake system not only ensures your safety but also promotes a smoother driving experience. Keeping your vehicle in good working condition creates a safer environment for you, your passengers, and other vehicles around you. 

It doesn’t take a lot of time or energy for brake mastery. Once you understand a little more about how the brake system works, you’ll be an expert at ensuring your car is well-maintained and safe for every drive you make.

Stopping Power 101: How Your Car’s Brakes Actually Work

December 14, 2023 by Denver Express Car Care

Did you love Saturday morning cartoons when you were young? The Flintstones is a classic. What kid doesn’t love the idea of having a dinosaur for a pet? Or using your feet to start and stop a car?

The concept seems a bit childish when you age and understand just how fast a car goes. Starting a car – maybe. If you’ve ever had to push a car to start it, you realize power comes from forward motion. 

But stopping – that’s altogether different. You need more than feet to stop a car. 

Driving here in Colorado, car brakes are an important part of our daily commute. Whether you sail in and out of the pickup line for your kids, or fly down the highway for a day of skiing with friends, life would be tricky (and treacherous) without brakes. 

But have you ever stopped to think about how they get their stopping power? What makes car brakes work? 

Let’s find out. 

Where car brakes started

The invention and development of car brakes can be attributed to several individuals over time. The early automobiles did not have effective braking systems, and the earliest forms of braking were rudimentary compared to modern standards.

One notable early advancement in automotive brakes was the introduction of mechanical brakes. In the late 19th century, various inventors and automobile pioneers began experimenting with braking systems. One such example is the application of mechanical brakes on the horseless carriage built by Karl Benz, the inventor of the first practical motorcar, in the late 1880s.

Stopping Power 101: How Your Car's Brakes Actually Work

However, the early braking systems were often primitive and unreliable. The transition from mechanical brakes to hydraulic brakes, which significantly improved braking efficiency and reliability, occurred over the early decades of the 20th century.

In 1918, Malcolm Loughead (later changed to Lockheed) introduced hydraulic brakes on the Duesenberg automobile. This marked a significant advancement in braking technology, providing more reliable and responsive braking compared to mechanical systems.

As the automotive industry continued to evolve, hydraulic brake systems became more widespread. The development of power-assisted brakes, such as vacuum-assisted and later hydraulic-assisted systems, further improved braking performance and control.

How today’s modern car brakes work

Modern car brake systems primarily rely on hydraulic mechanisms and friction materials to achieve effective deceleration and stopping. The prevalent disc brake system in contemporary vehicles comprises essential components such as brake discs or rotors, brake calipers, brake pads, and a hydraulic system. 

When the driver presses the brake pedal, a hydraulic process is initiated. This begins with the master cylinder, which contains brake fluid and pressurizes it upon pedal depression. The pressurized brake fluid is then directed through brake lines to the brake calipers at each wheel. 

In disc brake setups, the calipers house pistons that, when activated by the brake fluid, squeeze the brake pads against the rotating brake discs. These discs, attached to the wheel hub, generate friction when in contact with the brake pads, converting kinetic energy into heat and ultimately slowing down the vehicle. 

Brake pads are positioned on each side of the brake discs within the calipers. They play a crucial role in this process by providing the necessary friction. The heat produced is managed through ventilation slots in the discs and other cooling features to prevent brake fade. 

Additionally, modern cars often feature advanced systems such as Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), and Brake Assist to enhance safety and control during braking maneuvers. ABS prevents wheel lock-up by modulating brake pressure, while EBD optimizes the distribution of braking force among individual wheels. Brake Assist recognizes emergency braking situations and supplements braking force if the driver doesn’t apply sufficient pressure. 

Overall, modern brake systems are designed for efficiency, reliability, and safety, incorporating advanced technologies to deliver optimal performance.

Brakes work only as well as the driver behind them

According to the Office of Motor Vehicle Management, 98 percent of all car accidents are due to human error. 

Want to be a better driver? Until autonomous vehicles become the norm, the best way is to sharpen your driving practices. This is where you should start. 

  • Anticipate Stops – Be aware of traffic conditions, signals, and road signs well in advance. Anticipating stops allows you to brake gradually and smoothly.
  • Maintain a Safe Following Distance – Keep a safe distance from the vehicle in front of you. This provides you with more reaction time and space to stop safely.
  • Gradual Braking – Avoid abrupt or sudden braking, as it can lead to skidding or collisions. Gradually apply pressure to the brake pedal to slow down smoothly.
  • Avoid Overusing Brakes on Downgrades – On downhill slopes, use engine braking (shifting to a lower gear) where appropriate to reduce the load on the brakes. This helps prevent brake fade and overheating.
  • Check Brake System Regularly – Ensure that your vehicle’s braking system is well-maintained. Regularly check brake fluid levels, brake pads, and discs. Address any issues promptly.
  • Adapt to Road Conditions – Adjust your stopping distance based on road conditions. Wet or slippery surfaces may require increased stopping distances, so be mindful of the weather and road conditions.
  • Avoid Tailgating – Maintain a safe following distance to allow for unexpected stops by the vehicle in front of you. Tailgating reduces your reaction time and increases the risk of rear-end collisions.
  • Use Turn Signals – Use turn signals to indicate your intention to stop or turn. This alerts drivers behind you and improves overall road safety.
  • Stay Alert at Intersections – Be particularly vigilant at intersections. Look for pedestrians, cyclists, and other vehicles before proceeding or stopping.
  • Practice Defensive Driving – Stay aware of your surroundings, anticipate the actions of other drivers, and be prepared to react to unexpected situations.

And above all, check your brake system regularly. You can do this by paying attention to the way your brakes perform. Notice a difference in sound, touch, or odor? It’s time to bring it in for inspection. Have a dashboard light illuminated? Don’t ignore it; it’s a sign something is wrong. 

If you have a question, we’re here to help.

A Friend Mentioned Brake Line Inspection and Maintenance

November 14, 2023 by Denver Express Car Care

Have you ever laughed at some of the conversations you have with friends? One minute, you’re talking about what books are on your nightstand; the next, you’re discussing brake line inspection. Two wildly different topics, and yet both can educate you, entertain you, and give you vital information you need to move forward. 

If this sounds like it’s based on experience, it’s because it is. I recently sat across from a friend, talking about the latest fiction novel I was reading. It wove an intricate story of mystery and intrigue from a century ago. I highly recommended it, even pulled it from my bag and handed it to my friend. Then we got up, walked out of the coffee shop, and promised to get together again soon. 

That’s when she said, “I have to pick up my car from the repair shop. The brake line stopped working, and that was a crazy experience.” 

What?!

Of course, we stood there talking for a few extra minutes. I got a full education on how vital brake line inspection is, and how regular maintenance is vitally important. 

I’m so glad my friend is okay. As I drove away, I got to thinking about my own maintenance routines. I’m busy. I work full time. I tote the kids to school and practices. We love to venture into the mountains as a family on weekends. I may rely on my husband for car maintenance, but I also know that I’m the one who schedules it for my car in a way that works best for my lifestyle. 

Did my car need a brake line inspection? 

I did my research and learned what a brake line is

I didn’t want to get too technical. Frankly, I’m not that interested in auto mechanics. (My life is too busy!) But I knew my car is a vital tool in my life, and I wanted a little education. 

A Friend Mentioned Brake Line Inspection and Maintenance

A little research taught me that a brake line is a crucial component of a car’s brake system. It is responsible for carrying brake fluid from the master cylinder to the brake calipers (or wheel cylinders in drum brake systems) at each wheel. The brake line plays a vital role in transmitting hydraulic pressure to actuate the brakes, which in turn stops the vehicle. Here’s how a brake line fits into a car’s brake system:

Master Cylinder – The brake line starts at the master cylinder, which is typically located under the hood of the car, near the firewall. When you press the brake pedal, it generates hydraulic pressure in the master cylinder.

Brake Fluid Reservoir – The master cylinder is connected to a brake fluid reservoir, which provides a source of brake fluid. Brake fluid is a non-compressible hydraulic fluid that is used to transmit the pressure from the brake pedal to the brake components at the wheels.

Brake Lines – From the master cylinder, the brake lines carry the pressurized brake fluid to the wheels. Most cars have both front and rear brake lines, which split from the master cylinder to serve the front and rear brakes separately. These lines are typically made of steel or a high-strength, corrosion-resistant material to ensure durability.

Brake Calipers or Wheel Cylinders – At each wheel, the brake line connects to a component that applies the braking force. In disc brake systems, it connects to the brake caliper, which clamps down on the brake rotor when pressure is applied. In drum brake systems, the line connects to a wheel cylinder, which pushes the brake shoes against the inside of the brake drum.

Brake Fluid Pressure – When you press the brake pedal, it pushes a piston inside the master cylinder, which increases the pressure of the brake fluid. This pressurized fluid is then forced into the brake lines, traveling to the calipers or wheel cylinders at each wheel.

Brake Action – As the pressurized brake fluid reaches the calipers or wheel cylinders, it activates a mechanism that applies the brakes. In disc brakes, the caliper squeezes the brake pads against the rotor, creating friction and slowing down the vehicle. In drum brakes, the wheel cylinder pushes the brake shoes outward, causing them to press against the inside of the brake drum.

Braking Force – The resulting friction between the brake components and the wheel causes the vehicle to slow down and eventually stop. The force applied to the brake pedal is transmitted through the brake lines, ensuring the brakes respond to the driver’s input.

Release and Return – When the brake pedal is released, the pressure in the brake lines decreases, allowing the brakes to release. This enables the wheels to turn freely when not braking.

Too much info? What I really wanted to know

I read all of that, and it is interesting. But my basic takeaway was that brake lines are vitally important to my car’s braking system. And if something happens to the brake lines, a lot of things could happen:

Loss of Braking Power – A broken or malfunctioning brake line’s most immediate and noticeable effect is a loss of braking power. Without the ability to transmit brake fluid and hydraulic pressure to the brakes at the wheels, you’ll have difficulty slowing down or stopping the vehicle.

Increased Stopping Distance – A compromised brake line can significantly increase your vehicle’s stopping distance. This means you’ll need more time and distance to come to a complete stop, increasing the risk of accidents, especially in emergencies.

Uneven Braking – If one of the brake lines fails, the brake balance between the wheels can be disrupted. This can lead to uneven braking, causing the vehicle to pull to one side during braking, which can be hazardous, especially at high speeds.

Brake Fluid Leakage – A broken brake line allows brake fluid to leak out. Not only does this result in a loss of hydraulic pressure, but it also reduces the amount of brake fluid in the system, which can affect the operation of the brakes on other wheels.

Spongy Brake Pedal – If there is a brake fluid leak from a damaged brake line, air can enter the system. Air in the brake lines can cause a spongy or soft brake pedal, making it difficult to apply consistent and effective braking force.

Reduced Brake System Efficiency – When a brake line is compromised, the entire brake system’s efficiency is reduced. This means the brakes may not be able to generate enough force to stop the vehicle, increasing the risk of accidents and collisions.

Brake Overheating – In some cases, a damaged brake line may cause the brakes to overheat because they cannot release properly. Overheated brakes can result in brake fade, reduced braking effectiveness, and, in extreme cases, brake system failure. Not good when we’re coming home from a day of skiing. 

Loss of Brake Fluid – A broken brake line will lead to a significant loss of brake fluid. This not only impacts braking performance but can also result in air entering the brake system, requiring bleeding and re-pressurization of the brake system after the line is repaired or replaced.

Safety Hazards – The consequences of a failing brake line can be life-threatening. Inability to stop or slow down the vehicle can lead to accidents and collisions, endangering the lives of the driver, passengers, and others on the road.

And that’s what my takeaway is. 

Brakes are essential, even critical to my family’s safety. And the brake lines are a vital piece of the picture. 

Will I be scheduling periodic brake line inspections from now on? You bet!

My car is an essential tool in my daily life. And because my family’s lives mean everything to me, I now realize regular maintenance’s important role.  

I need an appointment … How about you?

Causes and Solutions of Brake Pedal Vibration

October 18, 2023 by Denver Express Car Care

You tap on the brake. Something’s not right. It shakes and shimmies. The brake pedal vibration is unnerving. 

Brake pedal vibration is not only uncomfortable, but also a sign of potential safety concerns. 

Drivers often describe it in different ways:

“It feels like a pulsating or throbbing sensation underneath my foot as I apply the brakes.”

“It’s a pronounced vibration every time I press down on the pedal.”

“It’s not just the brake pedal, I feel it in the steering wheel tool. The whole car shakes and feels like I might lose control.”

Some drivers even state the vibration is problematic, but the noise gets them. It’s a squeaking or grinding noise, and it worsens over time.  

What can you do? 

How the Brake Pedal Works within the Brake System

The brake system seems simple: tap the brakes, and the car stops. It’s a little more complex than that. 

When you press the brake pedal, you initiate a chain reaction that slows down or stops your car. 

It begins with the driver’s input—when you press the brake pedal, you exert force on it with your foot. This force triggers the master cylinder, which takes the force applied by your foot and transforms it into hydraulic pressure. This hydraulic pressure is subsequently moved through the brake fluid to reach the brake calipers (in disc brake systems) or wheel cylinders (in drum brake systems).

These brake calipers or wheel cylinders act as crucial intermediaries, engaging with the brake pads in disc brakes or brake shoes in drum brakes. They exert pressure on these friction materials, causing them to make contact with the brake rotors (in disc brakes) or brake drums (in drum brakes). As a result of this contact, friction is generated, and this frictional force effectively slows down or brings your vehicle to a complete stop. 

Causes and Solutions of Brake Pedal Vibration

To think it all starts with a tap on the brake pedal …

How Brake Vibration Occurs

Brake pedal vibration can be a troubling experience, and it usually indicates an issue somewhere in your vehicle’s braking system. The most common culprit is an uneven distribution of forces during braking. This can result from a variety of sources, including:

Uneven Brake Rotors – When the brake rotors (discs) are unevenly worn or warped due to excessive heat, it can lead to brake pedal vibration. This uneven surface causes the brake pads to make inconsistent contact during braking.

Poor Brake Pad Condition – Worn-out or improperly installed brake pads can create vibrations. When the pads aren’t sitting squarely against the rotor surface, it can cause pulsation in the pedal.

Alignment Issues – Poor wheel alignment can cause uneven tire wear, which, in turn, can lead to brake pedal vibration. Proper alignment ensures even distribution of braking forces.

Suspension Issues – A compromised suspension system can affect the vehicle’s ability to maintain a stable posture during braking. This can result in uneven braking forces and pedal vibration.

Worn-Out Brake Components – Over time, various brake components such as calipers, wheel cylinders, and brake hoses can deteriorate or become damaged. When this happens, it can affect the overall brake system’s performance and lead to pedal vibration.

How to Fix Brake Pedal Vibration

Think you’re experiencing brake pedal vibration? Recognition is the start of the solution. 

Bring it in, and we’ll get to the root cause, and fix it to bring your vehicle back to working condition. In most cases, a vibration usually requires one of the following maintenance items:

Brake Rotor Resurfacing or Replacement – If your brake rotors are unevenly worn or warped, consider having them resurfaced or replaced. This will ensure a smooth and even contact surface for the brake pads.

Brake Pad Replacement – If your brake pads are worn out or improperly installed, replace them with high-quality pads compatible with your vehicle’s specifications. Ensure that they are installed correctly to provide even contact with the rotors.

Alignment Check and Correction – Regularly check and adjust your vehicle’s wheel alignment to prevent uneven tire wear and subsequent brake pedal vibration.

Suspension Inspection and Repairs – Address any suspension issues promptly to maintain stability during braking. This can involve repairing or replacing worn-out suspension components.

Comprehensive Brake System Inspection – Periodically inspect your entire brake system by a qualified mechanic. This includes checking calipers, wheel cylinders, brake hoses, and other brake components for wear and damage.

How to Avoid Brake Pedal Vibration

Like other systems in your car, prevention is your best strategy for dealing with potential brake problems. To avoid brake pedal vibration, here are some proactive steps you can take:

Avoid Aggressive Braking – Try to avoid slamming on the brakes unnecessarily. Gradual and smooth braking reduces heat buildup and wear on brake components.

Use High-Quality Brake Parts – Invest in high-quality brake pads, rotors, and other brake components that meet or exceed your vehicle’s specifications. Quality parts tend to perform better and last longer.

Visit a Brake Specialist Regularly – Schedule regular brake inspections with a qualified brake specialist or mechanic. They can catch and address potential issues before they lead to pedal vibration or more severe brake problems.

Final words

Knowing more about brake pedal vibration and how your brake system works can make you more aware of potential problems early in the cycle. Instead of waiting for more damage to occur, you can bring your car in for maintenance and stop potential problems in their tracks. 

It’s important to note that brake pedal vibration is abnormal and usually indicates an issue within the braking system. Ignoring it can lead to safety concerns and further damage to brake components. If you experience brake pedal vibration, it’s advisable to have your vehicle inspected by a qualified mechanic to diagnose and address the underlying problem promptly.

Brake pedal vibration can be unsettling. Understanding its sources and following the recommended solutions can help you maintain a safe and comfortable driving experience.

How Brake Performance Impacts Your Drive

September 21, 2023 by Denver Express Car Care

When you drive, you might not think much about your brakes. You press down on the pedal, and they slow the car down. What else is there? 

A lot. 

When everything is working as designed, brake performance provides control. But when something goes awry, it can impact your drive in a variety of ways. 

What affects car brake performance?

Brake System Components – The components of the brake system itself play a significant role. This includes the brake pads, brake rotors (discs), brake calipers, and brake lines. If any of these components are worn out, damaged, or not functioning properly, it can lead to reduced braking performance.

Brake Fluid – Brake fluid is essential for transmitting the force applied to the brake pedal to the brake components. If the brake fluid is old, contaminated, or has air bubbles in it, it can lead to a spongy brake pedal feel and reduced braking effectiveness.

Braking Technique – How a driver applies the brakes can affect their performance. Abrupt or harsh braking can lead to excessive heat buildup and increased wear on the brake components, potentially reducing their effectiveness over time.

Vehicle Weight and Load – The weight of the vehicle and the load it’s carrying affect the amount of force required to bring the vehicle to a stop. Heavier vehicles or those carrying heavy loads may require more braking force to achieve the same level of deceleration.

How Brake Performance Impacts Your Drive

Speed – Braking at higher speeds generates more heat due to the increased kinetic energy that needs to be dissipated. Brakes are designed to handle a certain amount of heat, but continuous hard braking from high speeds can lead to brake fade, where the braking performance diminishes due to excessive heat buildup.

Road Conditions – The condition of the road surface can significantly impact braking performance. Wet, icy, or slippery roads reduce the friction between the tires and the road, making it harder to stop effectively.

Tire Condition – The quality and condition of the tires affect how well the vehicle grips the road when braking. Worn or improperly inflated tires can reduce braking effectiveness.

Brake Cooling – Brakes generate a lot of heat during braking. Adequate cooling mechanisms, such as ventilation slots, cooling ducts, or larger brake rotors, are necessary to dissipate this heat. Insufficient cooling can lead to brake fade.

Brake Pad Material – Different brake pad materials have varying friction characteristics. Some materials provide better performance in certain conditions but might wear faster. High-performance brake pads might offer improved stopping power but could wear out more quickly in everyday driving.

Maintenance – Regular maintenance, including brake inspections and servicing, is crucial for ensuring optimal brake performance. Worn-out brake pads, damaged components, or inadequate brake fluid levels can all negatively impact braking.

Brake System Design – The design of the brake system, including the size of the brake components and their compatibility with the vehicle’s weight and intended use, can influence overall braking performance.

Want better braking performance? Schedule your maintenance visits. 

Most brake performance issues start with a malfunctioning system. 

Of course, things can still go wrong even when you’re on top of maintenance items. When driving on an open road, you never know what might be in the path ahead. And that can impact your car’s functionality. 

Brake bias and how it impacts brake performance

Brake bias is the braking force distributed between the front and rear wheels of a vehicle. It’s an important aspect of brake system design that impacts how the vehicle behaves under braking. When you bring your vehicle in for a brake bias adjustment, it is to achieve optimal braking performance, stability, and control.

Brake bias, or brake balance, refers to the braking force percentage as it’s applied to the front wheels. This tracks the weight transfer that occurs during the braking process. Front-wheel-drive cars have a 70 to 80 percent brake bias, meaning 70 to 80 percent of the braking force is applied from the front brakes. For a rear-wheel-drive vehicle, it relies on a 60 to 70 percent brake bias. 

The impact of brake bias on brake performance is significant and can affect several aspects of the vehicle’s behavior:

Stability and Control – Proper brake bias helps maintain stability during braking. If the brake force is not properly balanced between the front and rear wheels, the vehicle could experience uneven weight transfer, leading to reduced stability and potentially causing skidding or loss of control.

Traction – Brake bias affects the traction available to each set of wheels. A poorly balanced brake system can result in wheel lockup (when a wheel stops rotating and skids) or reduced braking effectiveness on certain wheels, compromising overall stopping distance.

Lockup Prevention – Brake bias can help prevent wheel lockup. Front-wheel lockup can lead to loss of steering control, while rear-wheel lockup can cause the vehicle to spin. Adjusting brake bias can help avoid these scenarios.

Brake Wear – An unevenly balanced brake system can lead to uneven brake pad and rotor wear. This can result in premature wear on one set of brakes, necessitating more frequent replacement and potentially affecting overall braking performance.

Brake Performance – Brake bias impacts the distribution of braking force across all four wheels. Properly balanced brakes can provide consistent and effective braking performance in various driving conditions.

Brake Temperature – An imbalanced brake bias can lead to uneven heat distribution in the brake system. This could result in excessive heat buildup on certain wheels, potentially causing brake fade and reduced performance.

Your car is a delicate balance of finely tuned components

The next time you slide behind the wheel, you might take a moment and consider how thousands of parts come together to form a finely tuned vehicle that allows you to get where you want to go. 

In most cases, it does so with ease. Its functionality means that even when minor issues start to occur, it’s still designed to do its job well. 

But when things go awry anywhere within the braking system, it can severely limit your braking system’s performance. Regular maintenance can ensure everything stays in peak performance. 

It’s the easiest way to get the most out of your drive.

How Brake Fade and Overheating Affect Your Drive

September 14, 2023 by Denver Express Car Care

We tend to take our car’s brakes for granted. We rely on them, assuming they’ll always be there. And in fact, it’s very unusual for vehicles to suffer a total failure of the braking system. Less than 5 percent of all vehicle accidents are caused by brake failure. Still, considering there were over 5 million collisions during 2020, it adds up to a significant number of crashes where braking was part of the problem. 

Brakes are undoubtedly one of the most critical components when it comes to the safety of your vehicle and everyone on the road. They allow us to slow down and come to a complete stop, providing a sense of control essential for safe driving. But have you ever wondered what happens when your brakes don’t perform as expected? That’s where the phenomenon of brake fade comes into play. 

How Brakes Work

Before diving into the intricacies of brake fade, let’s quickly review how brakes work. When you press the brake pedal, a complex system of components springs into action to slow down or halt your vehicle. This system includes brake pads, rotors, calipers, and brake fluid. When you press the brake pedal, hydraulic pressure is created, which squeezes the brake pads against the spinning rotors. The friction between the pads and rotors generates the necessary force to bring your vehicle to a stop.

What is Brake Fade?

Brake fade is a phenomenon that occurs when the braking performance of your vehicle deteriorates due to excessive heat. When the brakes get too hot, they can lose efficiency and responsiveness, compromising your ability to slow down or stop the vehicle effectively. It’s like trying to stop a speeding train with a feather – not a situation anyone wants to find themselves in.

There are three primary types of brake fade: brake pad fade, dynamic brake fade, and brake fluid fade. Each type has its unique characteristics and causes.

Brake Pad Fade – This occurs when the friction material on the brake pads becomes too hot and loses its ability to grip the rotors effectively. It’s like a worn-out eraser struggling to erase pencil marks. High-speed or continuous braking can lead to brake pad fade.

Dynamic Brake Fade – Dynamic brake fade happens when the brakes heat up due to repeated heavy braking, causing the brake components to overheat and lose efficiency. It’s like a runner slowing down after a sprint due to muscle fatigue.

How Brake Fade and Overheating Affect Your Drive

Brake Fluid Fade – Brake fluid is essential for transferring the hydraulic pressure from the brake pedal to the brake components. However, when the brake fluid gets too hot, it can vaporize, forming air bubbles that compress and reduce the effectiveness of the hydraulic pressure. This is like trying to inflate a balloon with a leak – the pressure just won’t build up.

What Causes Brake Fade?

Brake fade is primarily caused by excessive heat buildup in the braking system. This can result from various factors, such as aggressive driving, driving downhill for extended periods, towing heavy loads, or even environmental conditions like hot weather. When the brakes heat up, they can’t dissipate the heat quickly enough, leading to a decrease in braking efficiency.

How to Prevent Brake Fade

The good news is that brake fade can be prevented with proper care and driving habits. Here are some tips to help you keep your brakes in optimal condition:

Avoid Aggressive Driving

Sudden and excessive braking generates a lot of heat, increasing the risk of brake fade. Maintain a safe following distance and anticipate stops to minimize the need for abrupt braking.

Engine Braking

When going downhill, consider using engine braking (downshifting) in combination with light brake application to help reduce the load on your brakes.

Use Lower Gears

When descending steep hills, use lower gears to control your speed. This reduces the strain on your brakes and prevents them from overheating.

Brake Fluid Maintenance

Regularly check and change your brake fluid as your vehicle’s manufacturer recommends. Fresh brake fluid has a higher boiling point and better heat resistance.

Quality Brake Components

Invest in high-quality brake pads, rotors, and calipers. These components are designed to handle heat better and provide more consistent performance.

Cool Down

If you’ve been driving aggressively or descending steep hills, take a break and allow your brakes to cool down before continuing your journey.

Proper Loading

If you tow a trailer or carry heavy loads, ensure your vehicle is within its recommended weight limits. Overloading can strain your brakes and lead to fading.

Avoid Riding the Brakes

Keeping your foot on the brake pedal, even lightly, can generate heat. Instead, release the pedal when not actively braking to let the components cool down.

What to Do if You Experience Brake Fade

Even with all the precautions, brake fade might still occur in certain situations. If you notice a sudden decrease in braking performance, here’s what you should do:

Stay Calm – Panicking won’t help. Keep a steady hand on the steering wheel and remain focused.

Downshift – If you’re driving a manual transmission vehicle, downshift to a lower gear to help slow down the vehicle.

Pump the Brakes – If you’re driving a vehicle with anti-lock brakes (ABS), gently pump the brake pedal to prevent the wheels from locking up.

Engage Emergency Brake – If you’re in a safe and controlled environment, use the emergency brake cautiously to slow down the vehicle.

How Common is Brake Fade?

Brake fade isn’t an everyday occurrence for most drivers, especially those who practice good driving habits and maintain their vehicles. However, it can still happen, especially in demanding situations, including navigating the Rocky Mountains. 

The key is to be aware of the factors contributing to brake fade and take preventive measures to minimize its occurrence.

Understanding brake fade and its different types are essential for maintaining safe driving conditions. Adopting proper driving techniques, regular maintenance, and using high-quality brake components, can significantly reduce the risk of brake fade. 

Brakes are your vehicle’s lifeline, so treat them with care, and they’ll keep you safe mile after mile.

How to Improve Stopping Power and Safety with Brake Maintenance

March 21, 2023 by Denver Express Car Care

What’s the stopping power of your car? How fast can you stop? Of course, that’s a loaded question. The answer is: It depends. It depends on:

  • How fast you’re driving
  • The maintenance of your vehicle
  • How old your brake system is
  • What weather conditions are currently
  • The make and model of the vehicle

Inherently we know that our cars will stop differently in July than in January. Hot streets create a different experience than a road covered in ice and snow. 

And while you might not think about your stopping power every time you jump behind the wheel, you might think about safety. You have a lot going on inside your vehicle. Safety is your number one concern. 

This is why brake maintenance should also be top of your list. Brakes keep you safe. Your ultimate goal is to improve stopping power to lower your risk.

What to know about stopping power

What do you need to know about your brakes stopping power? For most drivers, it’s a simple process. Tap on the brakes; the car slows down until it ultimately comes to a stop. 

How to Improve Stopping Power and Safety with Brake Maintenance

But there’s more to it than that. 

Stopping power measures what it takes to bring the vehicle to a stop. It’s the stopping distance as you face everyday driving conditions. Ultimately it depends on:

  • How well the brakes work when you tap on the brake pedal
  • How well a vehicle reacts when the brake pedal is pressed
  • Your perception of driving conditions
  • How well you react when you sense a change in driving conditions

In most cases, it takes about three-quarters of a second to perceive a change in driving conditions, and another three-quarters of a second to react and tap the brake pedal to start the braking process. That’s 1.5 seconds before the brakes start doing their job. At a standard 60 mph, your car can travel as much as 120 to 140 feet in that 1.5 seconds.

Once you start the reaction process, it’s the vehicle’s turn takeover. Dry pavement conditions will provide more stopping power than wet pavement. It can easily double or even triple the space needed to bring your vehicle to a complete stop. 

All of this is with a car in good working condition. Ignoring regular brake maintenance can increase the time needed to stop, putting you, your passengers, and those around you at risk.  

It’s time for brake maintenance

As you continue to drive your car, you’ll get comfortable with how it works. You’ll develop a relationship with it, understanding when it’s trying to communicate with you. 

Maybe you hear a strange noise you’ve never heard before. A light flashes on the dashboard. Or an odor becomes apparent when you step on the brakes. 

Your vehicle was designed with safety systems to alert you when problems arise. Rarely will systems fail on a dime. Instead, warning signals will be sent, alerting you to potential problems.  

If you notice these early, you have time to do something about them. Your brakes are one of the most important systems in your car. Watch for any of these problems. Then take action as soon as possible. 

Noisy brakes – Brake pads are the most commonly replaced items within the brake system. The pads are designed with a warning marker to alert you the brake pads are wearing down. You can’t miss this high-pitched squeal. Every time you step on the brake pedal, that squeal will remind you it’s time to replace your brake pads. Ignore it, and the noise will worsen. Wait too long, and it could do more damage to the brake system, possibly warping the rotors. This will increase your repair bill once you bring it in for replacement. 

Smelly brakes – It’s not based on sound alone; you’ll notice a smell along with it. As brake pads wear down and possibly impact the brake caliper, it may begin to produce a scent you won’t be able to ignore. It may be a chemical smell as the wear layer burns down, or a burning smell as the brakes heat up. If you notice it, it’s time to bring them in for maintenance. 

Soft brakes – You can’t miss this soft, spongy feel when you press down on the brake pedal. You’ll press down further to get the same job done. Moisture can accumulate in the brake fluid reservoir, allowing the brake fluid to boil from the heat generated as you drive. Air in the brake’s hydraulic system can delay the reaction time between pushing on the brake pedal and stopping. 

Hard brakes – The opposite is also true. If you push down on the brake pedal and it’s harder than usual, it’s a sign of misaligned brakes or a brake booster no longer functioning correctly. 

Tires – The reason you have trouble stopping might not be your brakes at all. Instead, it could be a tire that can no longer function as designed. When tire tread is too thin or too worn, it doesn’t have the traction to bring your vehicle to a stop. It won’t have the “bite” necessary to grip the road. Bad driving conditions only accelerate this problem. That’s why it’s good to have them checked occasionally. 

Are your brakes well maintained? 

Good brake maintenance starts with getting to know your car. It’s about feeling how it runs when operating well so that you know when something is off. 

There’s no denying that one of the most critical systems on your vehicle is your brakes. If they aren’t working correctly, your stopping power can quickly diminish. 

When was the last time you had your brakes checked and maintained? If it’s been a while, now may be the time. With quick servicing, our experts will ensure your vehicle is ready to face the challenges of the road ahead, no matter what the Colorado weather throws our way.

The Role of Sensors in Your Car’s Anti-Lock Brake System: Understanding How They Work

March 14, 2023 by Denver Express Car Care

Few systems on your vehicle are as critical as the brakes. They help keep your car under control. They help keep you safe. 

Since brakes were first developed, designers have worked to make them better. 

The very first cars were equipped with simple braking systems consisting of a lever or pedal connected to the wheels. These early brakes were not very effective, and they often failed to stop the car in a timely manner. With so few cars on the road, it had little effect. But it did spawn the next generation of brakes.

In the early 20th century, new technologies improved the performance of brakes. Drum brakes were introduced, which used brake shoes to press against the inside of the drum wheel. This design was more effective than the earlier mechanical brakes, and became the standard for most cars.

In the 1950s and 1960s, disc brakes were phased in. Disc brakes use a rotor attached to the wheel with brake pads that press against the rotor to slow down the car. This design is more effective than drum brakes and provides better stopping power. Disc brakes have now become the standard for most cars, and are used on both the front and rear wheels.

With more advanced materials and computer-aided design, braking systems continue to evolve. Today, you’ll find cars equipped with advanced braking technologies, including anti-lock braking systems (ABS), electronic brake force distribution (EBD), and brake assist (BA). These systems use sensors and computer-controlled actuators to optimize braking performance and improve safety.

What does the future hold? Electric vehicles (EVs) are bringing in new brake systems specifically designed for EVs. These systems use regenerative braking, which captures the energy generated by the car’s brakes and uses it to recharge the battery.

If there is a way to make the braking system safer, car designers are finding ways to implement the technology. Sensors are and will remain an essential part of overall car design. 

The Role of Sensors in Your Car's Anti-Lock Brake System: Understanding How They Work

The role of anti-lock brakes

You don’t have to go any further than the name to understand the role anti-lock brakes play in the braking system. Anti-lock brakes are designed to prevent the wheels from locking up. If you’ve ever experienced this on icy roads, you understand how dangerous it can be. Anti-lock brakes avoid skidding or loss of control. It helps decrease the braking distance to improve overall safety. 

The ABS keeps the tires connected to the road. Before ABS, pressing down hard on the brake pedal could lock the steering wheel and cause the wheels to skid. When you lose traction, you lose control.

ABS uses sensors to monitor the rotation of each wheel. It detects slippage, skidding, or wheel lock. When it encounters it on one or more wheels, the electronic control unit will send a signal to the hydraulic control unit, releasing braking pressure to improve the grip. With the lock position corrected, brake pressure is reapplied to keep the wheel connected and bring the car to a complete stop. 

How an anti-lock brake sensor works  

Anti-lock sensors are located at each wheel hub. These sensors constantly monitor the rotation of each wheel throughout the drive. They monitor every aspect of wheel cycling to see if any of them skid or lose control. 

Speed sensors calculate the revolutions and continuity between each wheel. If it detects differences, the ABS engages and takes over the braking. 

A speed sensor consists of a magnet wrapped in a coil, attached to a sensor ring connected to the CV joint hub. As these two meet, they create an electrical field that measures the number of pulses per second created between each coil and sensor ring. This converts to a digital signal that is transmitted to the ABS. The controller counts the pulses and evaluates when to control the braking. 

What can go wrong with the anti-lock brake sensors

Different cars will have different anti-lock brake sensor configurations, with most of today’s vehicles having a sensor attached to each wheel. With more parts means there are more chances for a component to fail, activating a potential problem that can impact you while you drive. 

With most vehicles, technology creates precise measurements and has a dynamic way of alerting you to potential problems. When an ABS sensor fails, it will warn you in several ways. 

The ABS light comes on

The most apparent alert system will occur right on your dashboard. The ABS light will come on, alerting you it’s detected an issue with the ABS. Think of the ABS light as a similar warning signal to the check engine light. It’s a check system that alerts you to minor changes, giving you plenty of time to schedule a visit with your mechanic to determine where the problem lies. Never ignore warning signals. They’re there for a reason. 

Braking changes

The goal for any driver should be to avoid heavy braking conditions whenever possible. Slamming on the brakes is never good, putting you, your passengers, and your car at risk. That said, systems like ABS are designed for unavoidable situations where hard braking is necessary. Over time, you may notice changes in the way your brakes respond. Does it take longer to react? Do you see tiny slips in what used to be flawless recovery? It might be an indicator of a problem with an ABS sensor. Since the ABS is crafted from just a few components, the problem may lie within the controller or the sensors. A mechanic can test both and find out exactly where the problem lies. 

Less stability under poor driving conditions

We’ve had our share of bad driving conditions this year. The ice and snow have lingered for what seems to be a long time. Over time, you’ve developed a sense of how your car performs under different weather conditions. This is where it pays to focus on your car’s performance. A properly functioning ABS will minimize any traction loss. If you experience any traction loss or feel a slight slippage, it might indicate an ABS sensor failing. This is often caused by a problem within the module, or a component of the sensor that needs replacing. 

The role of the anti-lock brake sensor – is yours working? 

Today’s modern conveniences keep us safer on the road. It’s also possible for more problems to occur over time as things wear down. 

When was the last time you had your car inspected? Schedule an inspection today if you think you have a problem with an anti-lock brake sensor. 

It’s the best way to keep you safe and out of harm’s way.
