How to Improve Stopping Power and Safety with Brake Maintenance

by

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

by

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. 

The Importance of Regular Anti-Lock Brake System Maintenance

by

Love puzzles? Want a challenge? The average car today has around 30,000 parts inside. The engine alone has thousands of tiny components that all come together to create a powerful display of energy that allows you to move throughout your days. 

Yet anytime you have that many parts coming together in one place, eventually, you’ll have a problem. If one bolt comes loose, it can bring an entire system to a grinding halt. And on a moving vehicle, that can be a big problem. 

Imagine your anti-lock brake system doesn’t work. It’s cold outside. The streets are icy. You tap the brakes – and they don’t work. 

That’s just one of the reasons maintenance is essential. If you pay attention to your anti-lock brake system before you need it, you’ll reduce the chances of having a problem when you need it most. Here’s what maintenance looks like on your anti-lock brake system. 

What are anti-lock brakes

Anti-lock brakes, also known as ABS, are a safety feature in today’s modern vehicles. They help prevent the wheels from locking up during sudden braking. While this technology was first introduced in the late 1920s, it wasn’t until the 1970s that ABS became widely available in consumer vehicles. 

When a vehicle’s wheels lock, the driver can lose control of the car. It can skid, making it difficult to steer or stop. Anti-lock brakes work by preventing this from happening. When the driver taps the brakes, ABS rapidly pumps the brakes, allowing the wheels to continue rotating. This allows the driver to maintain steering control, allowing the vehicle to move more quickly and safely.

The Importance of Regular Anti-Lock Brake System Maintenance

ABS is made up of several vital components. Wheel speed sensors are located at each wheel. They monitor the speed of the rotation, sending signals back to the ABS control module, which processes the information and determines if one or more wheels are locking up.

If the control module detects a wheel lock up, it sends a signal to the brake actuator, which rapidly pumps the brakes. The brake actuator uses a pump to pressurize brake fluid, which causes the brakes to be applied and released in rapid succession. This helps prevent the wheels from locking up, and allows the driver to maintain control of the vehicle.

Anti-lock brakes are beneficial during all low-traction conditions, such as rain, snow, or ice. When the roads are slippery, it’s easier for the wheels to lock up because there’s less friction between the tires and the road. ABS helps by keeping the wheels steady,  allowing the driver to maintain control of the car.

7 maintenance tips for your anti-lock brake system

Anti-lock brakes are a critical safety feature in modern vehicles that help prevent the wheels from locking up during sudden braking. Regular maintenance is essential to ensure that your anti-lock brakes are working properly. Here are seven maintenance items that you should do to keep your anti-lock brakes working well:

Check the brake fluid level

ABS relies on brake fluid to function correctly. The brake fluid level should be checked regularly, and topped off if necessary. If the brake fluid is low, it could indicate a leak in the system, which should be repaired as soon as possible. Remember, your ABS needs the right fluids to keep it running smoothly.

Inspect the brake pads and rotors

The brake pads and rotors are the components that come into contact with the wheels to slow them down. Over time, the brake pads will wear down, and the rotors may become corroded or damaged. Inspecting the brake pads and rotors will help you identify any issues before they become a problem. Think of it as a check-up for your ABS.

Check the wheel speed sensors

The wheel speed sensors are responsible for monitoring the speed of the wheels and sending signals to the ABS control module. If a sensor is faulty, the ABS system may not function properly. Check the sensors regularly for any signs of damage or wear and tear. These sensors are the eyes of your ABS, so make sure they’re working.

Check the ABS control module

The ABS control module is the brain of the system. It’s responsible for processing the information from the wheel speed sensors and determining if one or more wheels lock up. If the control module is malfunctioning, the ABS will not work. It’s essential to keep the brain of your ABS in good shape.

Check the brake actuator

The brake actuator is a hydraulic component that uses a pump to pressurize the brake fluid, which causes the brakes to be applied and released in rapid succession. Check the brake actuator for any signs of damage or wear and tear. This is the muscle of your ABS, so make sure it’s functioning.

Check the brake lines and hoses

The brake lines and hoses deliver brake fluid from the master cylinder to the brakes. Check the cables for any signs of leakage, cracking, or damage. These are the veins of your ABS, they need to be in good condition to function correctly.

Have the ABS inspected by a professional

Have your ABS inspected by a professional mechanic regularly. They will have the proper tools and knowledge to diagnose issues with the system and make necessary repairs. Always consult your vehicle’s owner’s manual for recommended maintenance schedules and guidelines.

It’s also worth mentioning that if the ABS warning light comes on in your vehicle’s dashboard, it’s an indication that there may be an issue with the ABS and you should take it to a professional to diagnose and repair the problem as soon as possible.

When was the last time you scheduled a maintenance visit for your anti-lock brake system?

Regular maintenance is essential to ensure that your anti-lock brakes are working properly. It ensures that your anti-lock brakes are always ready to perform when needed. 

Remember to consult your vehicle’s owner’s manual for recommended maintenance schedules and guidelines. Not sure when they were last inspected? Don’t put it off; schedule it today. 

It’s the best way to ensure your vehicle is safe whenever you take it out for a drive. 

Brake Fluid Leaks: How to Identify and Fix Them

by

Drip. Drip. Drip. 

It’s something you might not notice right away. But eventually, you’ll discover your vehicle is leaking. What is it? What does it mean?

Cars use a variety of fluids to keep them operational:

  • Motor oil
  • Coolant
  • Brake fluid
  • Transmission fluid
  • Power steering fluid
  • Windshield washer fluid
  • Gasoline

Try and operate your vehicle without one of these essential fluids. It won’t happen. It’s up to you to ensure all systems work well, and the fluids are at proper levels. 

Including brake fluid. Brake fluid leaks can not only impact your brake system’s functionality but can also put you at risk. Imagine driving down the mountain after a day of skiing, and your brakes no longer work. 

With so much riding on your brake system, here are a few things to consider if you find a brake fluid leak.

How brake fluid keeps the brake system operational 

Brake fluid is a crucial component of a vehicle’s brake system. It is responsible for transmitting power from the brake pedal to the brake calipers to the brake pads, slowing the wheels down. 

Brake Fluid Leaks: How to Identify and Fix Them

The brake system is closed, meaning that brake fluid is sealed inside and doesn’t typically need to be refilled the way you do motor oil or coolant. However, over time, the fluid can become contaminated or lose effectiveness, leading to decreased braking performance or even failure.

Brake fluid is typically made of a glycol-based fluid designed to withstand high temperatures and maintain viscosity over time. When the brake pedal is pressed, the brake fluid is forced through small passages in the brake lines and calipers. The brakes may not function properly if the fluid doesn’t flow easily.

The brake fluid also acts as a lubricant for the various moving parts in the brake system, such as the brake calipers and the brake pads. This helps to prevent wear and tear on these parts and keeps the system running smoothly. The brake fluid is also responsible for protecting the brake system from corrosion by forming a protective barrier on the metal components.

Brake fluid is hygroscopic, which means it absorbs moisture over time. This can decrease the fluid’s boiling point, which can cause brake fade or failure. Therefore, it is important to have the brake fluid checked regularly, and to replace it if necessary.

Check your owner’s manual for guidance, but brake fluid should generally be replaced every two to three years. Some manufacturers recommend replacing the brake fluid more often, such as every 30,000 miles or so. Replacing the brake fluid can help to ensure that the brakes are in good working condition and can help to prevent costly repairs down the road.

What can cause brake fluid to go bad?

Brake fluid is an essential component of a vehicle’s brake system, responsible for transmitting force from the brake pedal to the brake calipers, eventually slowing the wheels down and bringing the car to a stop. However, brake fluid can become contaminated over time or lose effectiveness, leading to decreased braking performance or even failure. Understanding the causes of brake fluid deterioration is essential to ensure that the brake system is functioning correctly and prevent costly repairs.

One of the most common causes of brake fluid deterioration is exposure to moisture. Brake fluid is hygroscopic, which means it absorbs moisture over time. This can decrease the fluid’s boiling point, which can cause brake fade or failure. Moisture can enter the brake system through the brake lines, calipers, and other components. This can happen due to leaks in the design, condensation due to temperature changes, or even through the brake fluid reservoir itself.

Brake fluid deterioration can also happen when exposed to high temperatures. As brake fluid is forced through the brake lines and into the brake calipers, it is subjected to high temperatures. This extreme heat can cause the fluid to break down, leading to decreased effectiveness and a reduced ability to lubricate the moving parts in the brake system. High temperatures can also cause the fluid to boil, resulting in brake fade or failure.

Contamination can also occur. This comes from rust, dirt, or other particles entering the brake system. These contaminants can cause the brake fluid to become dirty or discolored, reducing its effectiveness and leading to decreased braking performance. Contamination can also cause the brake system to wear out more quickly, leading to costly repairs.

Like other car parts, age will eventually become a factor. Over time, brake fluid will lose its effectiveness and can become contaminated. This can happen as a result of the fluid absorbing moisture, becoming polluted with dirt or other particles, or simply due to the age of the liquid. Replace the brake fluid periodically, even if it appears to be in good condition.

Brake fluid can also fail due to a lack of maintenance. The brake fluid can be compromised if the brake system is not maintained correctly. This can happen due to not checking and replacing the liquid regularly, not properly cleaning and inspecting the individual components in the brake system, or not correctly lubricating the moving parts. One part feeds to another; a regular maintenance schedule will ensure everything is working well.  

Have a brake fluid leak? 

Brake fluid is typically a light yellow color, but it will darken to  gold or brown with age. If you see it underneath your car, or notice it accumulating in your wheel wells, it’s a sign of a leak. 

It could be coming from any component within the brake system. It could be a failure of any part at any time. 

But there’s one surefire way to prevent failure and deterioration before it starts; have brake fluid checked regularly, and replace it if necessary.

Start by checking your owner’s manual for guidelines. Then schedule a maintenance visit with one of our mechanics to be sure that the leak isn’t a sign of a bigger problem.

Top 3 Reasons Why Your Car’s Anti-Lock Brake System May Be Malfunctioning

by

Many safety systems built into today’s vehicles are ever-present, always working to keep you safe. 

Yet over time, small changes become noticeable, and you start to wonder if these safety features will work when an emergency presents itself. 

Your anti-lock brake system may be one you think little about. But when you use it while braking hard or skidding on ice, you know just how valuable the technology is. 

How do you know if it’s malfunctioning? 

How anti-lock brake system works

An anti-lock brake system (ABS) comprises several key components, including wheel speed sensors, an electronic control unit (ECU), and solenoid valves. The wheel speed sensors are located at each wheel and are responsible for sending information about the speed of each rotation to the ABS control module. The ECU, or brain of the system, receives this information and uses it to determine whether the wheels are about to lock up.

When the driver applies the brakes, the ABS begins to monitor the speed of each wheel. If the ECU detects that one or more wheels are about to lock up, it sends a signal to the solenoid valves. These valves are located at each brake caliper and are responsible for controlling the pressure of the brake fluid. The solenoid valves will rapidly open and close, releasing and reapplying pressure to the brake fluid. This helps to prevent the wheels from locking up, allowing the driver to maintain steering control.

Top 3 Reasons Why Your Car's Anti-Lock Brake System May Be Malfunctioning

The process of the ABS releasing and reapplying brake pressure is called “pumping” and it happens very quickly, within milliseconds. This rapid pumping action causes a pulsation in the brake pedal, which the driver can feel. This is normal and a sign that the ABS is working correctly.

ABS systems also have an indicator light on the dashboard that will illuminate if there is an issue. This light will typically come on when the vehicle is started and will go off shortly after. If the light stays on, it may indicate a malfunction in the system. This gives you advanced warning that it’s time to take your car to a mechanic for inspection.

Is the ABS always in use?

Think of the anti-lock brake system as a separate component of your vehicle’s brakes. Anti-lock brake systems are designed to help drivers maintain steering control during hard braking by preventing the wheels from locking up. This technology has been around since the late 1970s and is now a standard feature on most vehicles.

The anti-lock brake system is designed for emergency braking situations, where the driver needs to maintain steering control while braking hard. However, ABS is only sometimes in use.

When the driver is braking normally, the ABS is not active. The brake system works as it would in a vehicle without ABS. The brake pads make contact with the rotors, slowing the vehicle down. The driver controls the brake pedal pressure and can adjust it as needed.

The ABS only becomes active when the driver applies the brakes hard, and the system detects that one or more wheels are about to lock up. When this happens, the ABS rapidly pumps the brakes, releasing and reapplying pressure to the brake fluid in order to prevent the wheels from locking up. This allows the driver to maintain steering control while braking hard. The ABS is active only for a short period of time, typically a few seconds, and then the system goes back to normal braking mode.

It’s worth noting that ABS is not only active when the driver applies the brakes hard. The system also monitors the speed of each wheel even when the driver is not braking. In some cases, if the system detects any abnormal behavior, it will act accordingly.

In addition, some newer vehicles may have an advanced version of the ABS, called Electronic Stability Control (ESC). This system uses sensors to detect when a vehicle is about to lose control and applies brakes to individual wheels to help the driver regain control. ESC is always active, even when the vehicle is not braking.

3 reasons why your car’s anti-lock brake system may be malfunctioning

There are safety systems built into your braking system to alert you when you have a potential problem with ABS.

Worn brake pads

Over time, brake pads wear down, becoming thinner and less effective at stopping the vehicle. This can cause the ABS to work harder and can also lead to decreased braking performance. If the pads are worn to the point where they are no longer effective, the ABS may not be able to function properly, and the ABS warning light may come on. It is important to have the brake pads inspected and replaced as needed to ensure that the ABS is working properly.

Failed wheel speed sensors

The wheel speed sensors are responsible for sending information about the speed of each wheel to the ABS control module. If one of these sensors fails, the ABS may not be able to control the brakes. This can cause the ABS warning light to come on and can also lead to decreased braking performance. In some cases, a failed wheel speed sensor may also cause the vehicle’s traction control system to malfunction. Symptoms of a failed wheel speed sensor include the ABS warning light coming on, the traction control light coming on, and decreased braking performance.

Electrical issues

The ABS is controlled by an electronic control unit (ECU) which receives input from the wheel speed sensors and the brake pedal. If there is an issue with the wiring or the ECU itself, the ABS may not function properly. This can cause the ABS warning light to come on and can also lead to decreased braking performance. Electrical issues can be caused by a variety of things, including a faulty ABS control module, damaged wiring, or a problem with the vehicle’s computer. Symptoms of an electrical issue with the ABS include the ABS warning light coming on and decreased braking performance.

Is there a problem with your anti-lock brakes?

While very few car accidents are caused by total brake failure, it still can be a scary experience to lose control for even a moment. By keeping your entire braking system functioning well throughout its life, you’re less likely to experience problems. 

It’s essential to have your vehicle inspected by a qualified mechanic if you notice any issues with your brakes to ensure that your vehicle is safe to drive.

5 Common Symptoms of a Failed Car Anti-Lock Brake System

by

Today’s modern vehicles are filled with new technology that makes them safer, more intuitive, and more fun to drive. 

With over 10,000 parts working to give you this expanded driving experience, it also means more parts can fail over time. 

Few would argue that the braking system is one of the most critical. Anti-lock brakes work to improve braking in stressful, emergency situations. They’re designed to keep you safer while driving and stopping on your daily commute. 

How do you know when they start to fail? How do you know when the anti-lock brake system should be replaced? You may notice several common symptoms that signal it’s time for an inspection. 

How anti-lock brake systems work

Anti-lock brake systems, or ABS for short, are a safety feature in many modern vehicles. These systems are designed to prevent the wheels of a vehicle from locking up during hard braking, which can cause the vehicle to skid and potentially lose control. 

The basic principle behind ABS is that it allows the wheels of a vehicle to continue to rotate while braking, rather than locking up and skidding. To accomplish this, ABS systems use sensors, valves, and pumps to detect when a wheel is about to lock up and then rapidly pump the brake fluid to that wheel to reduce the braking force. This allows the wheel to continue to rotate, which helps the driver maintain control of the vehicle during hard braking.

5 Common Symptoms of a Failed Car Anti-Lock Brake System

The first step in the ABS process is the detection of wheel lockup. Sensors located on each wheel measure the wheel’s rotational speed. If a sensor detects that a wheel is rotating slower than the others, it indicates that the wheel is about to lock up and skid.

Once a sensor detects a potential lockup, ABS activates the valves that control the brake fluid flow to that wheel. These valves rapidly open and close, allowing the brake fluid to flow to the wheel and then quickly release it, reducing the braking force on the wheel. This rapid pumping of the brake fluid is known as “pulse modulation.”

The result of this process is that the wheel can rotate rather than lock up and skid. This allows the driver to maintain control of the vehicle during hard braking and can help prevent accidents..

In addition to preventing wheel lockup and skidding, ABS systems also provide other benefits to drivers. For example, they can help drivers maintain steering control during hard braking, which can be especially useful in emergencies. Additionally, ABS systems can shorten the stopping distance of a vehicle, which can be especially useful on wet or slippery roads.

Overall, anti-lock brake systems are a valuable safety feature that can help drivers maintain control of their vehicle during hard braking and prevent accidents. While ABS systems have been standard equipment on many vehicles for several decades, they continue to be refined and improved to provide even greater benefits to drivers.

Common symptoms of failed anti-lock brake system

A car’s anti-lock brake system (ABS) is an important safety feature that helps prevent the wheels from locking up during sudden braking. However, like all mechanical systems, the ABS can malfunction and cause a variety of problems. 

Warning Light

One of the most apparent signs of a failed ABS is the illumination of the ABS warning light on the dashboard. This light is usually located near the speedometer and will turn on when there is a problem with the ABS. If the warning light comes on, it is essential to have the vehicle checked by a mechanic as soon as possible.

Reduced Braking Performance

If the ABS is not working properly, the vehicle’s braking performance may be reduced. This can make it more difficult to stop the car in a timely manner, which can be especially dangerous in emergency braking situations. Drivers may notice that the brakes feel “spongy” or that the car takes longer to come to a stop.

Pulling to One Side

If the ABS is not working correctly, the vehicle may pull to one side while braking. This can be caused by a malfunctioning wheel speed sensor or a problem with one of the brake calipers. It is vital to have the vehicle checked by a mechanic if this symptom is noticed, as it can be dangerous to drive a car pulling to one side.

Grinding or Growling Noise

If the ABS is not working properly, a grinding or growling noise may be heard when the brakes are applied. Worn brake pads or a malfunctioning ABS module can cause this. It is crucial to have the vehicle checked by a mechanic if this symptom is noticed, as it can indicate that the brake pads need to be replaced or that the ABS needs to be repaired.

Vibration in the Brake Pedal

If the ABS is not working properly, a vibration may be felt in the brake pedal when the brakes are applied. A problem with the brake rotors or a malfunctioning ABS module can cause this. A mechanic must check the vehicle if this symptom is noticed, as it can indicate that the brake rotors need to be replaced or that the ABS needs to be repaired.

It’s important to remember that these symptoms can also be caused by problems other than a failed ABS. However, if any of these symptoms are noticed, a mechanic must check the vehicle as soon as possible. A failed ABS can significantly reduce a vehicle’s braking performance and make it more difficult to stop the car promptly. Regular maintenance and inspection of the ABS can help prevent these problems from occurring in the first place.

Conclusion

ABS systems are an essential safety feature in modern cars, and a failed ABS can cause a variety of problems. If you notice any of these symptoms, it’s important to have your vehicle checked by a mechanic as soon as possible. Regular maintenance and inspection of the ABS can help prevent these problems from occurring in the first place.

Brake Noises: What They Mean and How to Fix Them

Do you remember the first time you slid behind the wheel of your current vehicle? It had a particular sound; it performed in a certain way. 

As the weeks and months roll by, you may start noticing things changing. There’s a new noise. Or you have to press down on the brake pedal more for the same performance level. 

These are warning signs designed to keep you safe. If you pay attention to these changes, you can bring your car in for an inspection and locate minor issues that are easy to repair. It prevents the problems from escalating into major repairs. 

How today’s modern car brake systems work

Modern car brake systems use a combination of friction, vacuum assistance, and electronic control to slow and stop a vehicle. The most common brake system in cars today is the disc brake system.

The disc brake system consists of a rotor attached to the wheel hub, and a caliper, which houses the brake pads. When the driver presses the brake pedal, brake fluid is sent under pressure through the brake lines to the caliper. The caliper then uses pistons to press the brake pads against the rotor, creating friction and slowing the wheel.

Brake Noises: What They Mean and How to Fix Them

Disc brakes are more efficient than drum brakes, commonly used in older cars. Disc brakes can dissipate heat better, which allows them to maintain their braking power even in heavy use. Additionally, disc brakes are less likely to suffer from brake fade, which is the loss of braking control due to overheating.

In addition to the friction created by the brake pads, many modern cars also feature a vacuum assist mechanism. This mechanism uses the vacuum created by the engine to provide additional force on the brake pedal, making it easier for the driver to brake.

They can also feature electronic control systems that help optimize braking performance. 

Anti-lock braking systems (ABS) use sensors to detect when a wheel is about to lock up, and modulate the brake pressure to prevent the wheel from locking.

Or they use Electronic Stability Control (ESC), which helps to improve a vehicle’s stability by detecting and reducing loss of traction. The system applies the brakes to individual wheels and can reduce engine power when the driver loses control of the vehicle.

The most common brake noises

Car brakes are an essential safety feature of any vehicle, and it is important to pay attention to any unusual noises or sensations when braking. Below are some common brake noises and what they may indicate, as well as potential solutions for each problem.

Squealing or screeching

If your brakes make a high-pitched squealing or screeching noise, it is likely that the brake pads are worn and need to be replaced. A small metal tab causes this noise, called a wear indicator, that rubs against the rotor when the pads are worn down. It is crucial to address this issue as soon as possible, as worn brake pads can reduce braking effectiveness and increase stopping distance.

Grinding

A grinding noise when braking signifies that the brake pads are worn down to the metal. The metal of the rotor is pressing into the metal of the caliper, causing damage to both components. This is a serious issue that should be addressed immediately, as driving on worn-out pads can cause expensive damage to the rotors and calipers and significantly decrease braking performance.

Clicking

A clicking noise when braking can be caused by several issues, such as worn-out brake pads, a loose brake caliper, or a problem with the brake pad guides. In most cases, this noise can be resolved by replacing worn brake pads or tightening loose components. However, if the clicking persists, it is best to have the vehicle inspected by a professional mechanic to determine the cause.

Rumbling

A rumbling noise when braking can be caused by warped rotors. This can happen if the rotors get too hot due to excessive braking or hard driving, causing the metal to warp and lose its smooth surface. Warped rotors can be resurfaced or replaced to fix the issue.

Sinking Pedal

If the brake pedal sinks to the floor when pressed, it may indicate a problem with the brake system’s vacuum booster or a leak in the brake lines. This issue can be dangerous, leading to a loss of braking power. It is important to have the vehicle inspected by a professional mechanic as soon as possible to determine the cause and find a solution.

In general, it is recommended to have your brakes regularly inspected by a professional mechanic to ensure that they are in good working condition. This will help to identify any issues before they become more serious and expensive to repair. Additionally, always pay attention to any unusual noises or sensations when braking, and have the vehicle inspected if you notice anything out of the ordinary.

Are your brakes making a funny noise?

It’s a sign you might have a problem that could put you and your passengers at risk. 

Brake noises can indicate a variety of problems, from worn brake pads to more serious issues, such as warped rotors. It is essential to pay attention to any unusual noises or sensations when braking, and to have the vehicle inspected by a professional mechanic to determine the cause and find a solution. Regular brake inspections can also help identify any issues before they become more serious and expensive to repair.

How to Spot the Signs of Brake Wear and Tear Before It’s Too Late

by

Some vehicle problems are easy to spot. If your tire is flat, you can see it. 

Some vehicle problems are more complex. If your brake pads are wearing down, you can’t see it just by walking up to your car. 

Manufacturers know this, and build in safety systems to alert you to potential issues. This is especially important with a vehicle’s brake system. It allows you to spot the signs of brake wear and tear before it puts you in danger. 

How a car’s brake system works

A car’s brake system is an essential safety feature that allows the driver to bring the vehicle to a stop or slow it down as needed. The brake system consists of several components, including the brake pedal, brake booster, master cylinder, brake lines, calipers, and rotors. Here’s a closer look at how each of these components works together to bring a car to a stop.

The brake pedal is the first point of contact for the driver when they want to activate the brake system. When the driver pushes down on the brake pedal, it activates the brake booster, which uses a vacuum to amplify the force applied by the driver. The brake booster increases the pressure applied to the master cylinder, a hydraulic pump that converts the mechanical energy the brake pedal uses into hydraulic pressure.

How to Spot the Signs of Brake Wear and Tear Before It's Too Late

The hydraulic pressure generated by the master cylinder is transmitted through the brake lines to the calipers located at each corner of the vehicle. The calipers house the brake pads, which are made of high-friction material. They press against the rotors (also known as brake discs) when the brakes are applied. The rotors are mounted to the wheels. They are responsible for dissipating the heat generated by the friction between the brake pads and the rotors.

When the brake pads make contact with the rotors, the rotors slow down, and the vehicle’s kinetic energy is converted into thermal energy (heat). The heat generated by the braking process is dissipated through the calipers and the rotors, which helps to prevent the brake system from overheating.

There are several types of brake systems used in modern vehicles, including hydraulic disc brakes, hydraulic drum brakes, and electric brakes. Each type of brake system has its own unique set of components, but they all work on the same basic principle of converting mechanical force into hydraulic pressure to apply the brakes.

How to spot the signs of brake wear and tear

As a driver, it is important to regularly check the condition of your brakes to ensure that your vehicle is safe to drive. Brake wear and tear is an everyday occurrence and can happen gradually over time, but it is essential to catch the signs early on to avoid more severe problems in the future. Here are some things to look out for to spot the signs of brake wear and tear:

Squealing or grinding noises: If you hear a high-pitched squealing noise while braking, it could be a sign that your brake pads are worn down and need to be replaced. Similarly, a grinding noise could indicate that your brake pads are completely worn out and the metal backing plate is now rubbing against the rotor. This can cause serious damage to your rotors, so it is important to address this issue as soon as possible.

Vibrations while braking: If you feel vibrations in the pedal or steering wheel while braking, it could be a sign that your brake rotors are warped. This can be caused by heat buildup from excessive braking or from the rotor being worn down unevenly. It is vital to have your rotors checked and possibly replaced to avoid further damage.

Soft or spongy brake pedal: If you press on the brake pedal and it feels soft or spongy, it could be a sign of a brake fluid leak. Brake fluid is essential for properly functioning brakes, so it is crucial to address this issue as soon as possible.

Pulling to one side while braking: If your car pulls to one side while braking, it could be a sign of a stuck caliper or an unevenly worn brake pad. This can cause your car to lose control while braking, so it is vital to have this issue addressed by a mechanic.

Brake warning light: If your brake warning light comes on, it could be an indication of a problem with your brakes. This could be anything from a low brake fluid level to a brake pad or rotor problem. It is essential to have this issue checked by a mechanic as soon as possible to avoid further damage to your brakes.

Is it time to have your brakes evaluated?

A car’s brake system is a complex but essential safety feature that allows the driver to bring the vehicle to a stop or slow it down as needed. The brake system uses a combination of mechanical and hydraulic components to apply the brakes and bring the vehicle to a halt, while also dissipating the heat generated by the braking process to prevent overheating.

If you detect any of the potential problems listed above, it’s time to have your brakes inspected. An inspection will allow a mechanic to evaluate each part of the system, discovering minor repairs that can be made before they escalate into bigger problems.

The Cost of Brake Repair: Is It Worth It to Fix Your Brakes or Replace Them?

by

What’s that sound? Why are my brakes so touchy when I push down on the brake pedal? When your brakes have problems, you’ll know it by paying attention to a change in behavior.

That’s by design. Brakes are arguably one of the essential systems in today’s modern vehicles. Imagine coming off the mountain after a day of skiing without the ability to use your brakes. It would be a harrowing experience at best. 

Still, how do you know what to do? Who should you trust? You know the cost of brake repair is going to take a bite out of your wallet. But what’s better: fix your brakes or replace them?

How brakes work

The braking system in a car is an essential safety feature that allows the vehicle to slow down or stop when the driver presses the brake pedal. 

When the brake pedal is pressed, a lever called the brake pedal pushrod activates the master cylinder, a hydraulic pump. The master cylinder pressurizes the brake fluid stored in a reservoir. The pressurized brake fluid is then sent through a series of tubes and hoses to the brake calipers located at each wheel.

The Cost of Brake Repair: Is It Worth It to Fix Your Brakes or Replace Them?

Inside the brake caliper, there are one or more pistons that are activated by the pressurized brake fluid. The pistons push against the brake pads and squeeze against the brake rotor. This creates friction, which slows down the rotation of the wheels, bringing the car to a stop. 

The brake pads and rotors can get very hot during this process, so most cars are equipped with a cooling system to dissipate the heat.

Some cars also have a brake booster, a vacuum-assisted device that helps the driver apply the brakes more easily. The brake booster uses the vacuum created by the engine to multiply the force applied by the driver’s foot on the brake pedal.

The brake system converts the moving vehicle’s kinetic energy into heat energy through friction, slowing down the car and bringing it to a stop. It is a complex system that requires regular maintenance and inspection to ensure it functions correctly.

Signs your brake system has a problem

As a car owner, it is important to regularly check and maintain your vehicle to ensure its safety and longevity. One key component to check is your brakes, as they are essential to your car’s overall function and safety.

There are several signs that your car may be experiencing brake problems. Here are some things to look out for:

  • Squealing or grinding noises: If you hear squealing or grinding noises when you apply the brakes, this could be an indication that your brake pads are worn down and need to be replaced.
  • Soft or spongy brake pedal: If you press the brake pedal and it feels soft or spongy, this could be a sign that there is air in the brake lines or that the brake fluid is low.
  • Vibrations when braking: If you feel vibrations in the brake pedal or steering wheel when braking, this could be a sign of warped brake rotors.
  • Pulling to one side while braking: If your car pulls to one side while braking, this could be a sign of a stuck caliper or an uneven brake fluid distribution.
  • Brake warning light: If the brake warning light on your dashboard is illuminated, this is a sign of a problem with your brakes.

If you notice any of these issues, it is vital to have your brakes checked by a mechanic as soon as possible. Neglecting to do so could result in further damage to your brakes, which can be costly to repair.

In addition to watching for warning signs, it is also important to regularly check your brake fluid level and to have your brakes inspected and serviced according to the manufacturer’s recommended schedule. This will help ensure that your brakes are in good working order and can help prevent more serious problems from occurring.

If you do need to have your brakes repaired, be sure to use a reputable mechanic and only use high-quality brake parts. Using cheaper, inferior parts can result in further problems down the road.

Should you fix your brakes or replace them?

How do you know if you should fix or replace your brakes? You can start by assessing the current condition of your braking system. 

  • Age of the brakes: If your brakes are older and have been in use for a long time, they may be more prone to wear and tear and may need to be replaced.
  • Condition of the brakes: If your brakes are heavily worn or damaged, it may be more cost-effective to replace them rather than trying to fix them.
  • Cost of repair: If the cost of repairing your brakes is close to or more than the cost of replacing them, it may make more sense to replace the brakes.
  • Frequency of use: If you use your brakes frequently, such as in stop-and-go traffic or on hilly terrain, they may wear out more quickly and need to be replaced more often.
  • Driving habits: If you have a tendency to brake hard or ride your brakes, your brakes may wear out more quickly and need to be replaced more often.
  • Vehicle make and model: Some makes and models of vehicles may have brakes that are more prone to wear and tear, and may need to be replaced more frequently. Check your owner’s manual for more details.
  • Overall condition of the vehicle: If your vehicle is older and has high mileage, it may be more cost-effective to replace the brakes rather than trying to fix them.

Ultimately, the decision to fix or replace your brakes will depend on a variety of factors, including your own personal situation. It’s always a good idea to have a mechanic inspect your brakes regularly to ensure they are in good working condition, and to replace them if necessary to ensure the safety of your vehicle.

Building a relationship with a reputable mechanic will give you the assurance you need to rely on their opinions, and make the right decision for your situation.

Why Your Brake Pads May Be Wearing Unevenly

by

What’s one of the most important systems on your vehicle? “Brakes” should be at the top of the list. 

Imagine driving through town without working brakes. Think about coming home from a day of skiing, tapping on the brake pedal, and nothing happens. Yep, the brake system is critical. 

Yet much of the brake system is hidden from view. You trust it’s there working and doing its job. You can see the tires, noticing if they’re flat or bald. You can tap the brake pedal and feel the pressure. But what about the rest of the system?

Brake pads are crucial for overall operation. Their uniform thickness controls how they operate. If your brakes aren’t performing as well as they should, it may stem from brake pads wearing unevenly. 

What are brake pads

The original braking system was nothing more than a block of wood. When a driver wanted to slow the car, they pushed a lever that moved a wooden block against the wheels. The friction was enough to slow and stop the car. 

However, that system quickly failed as cars became faster. Brakes got more sophisticated as our technology increased. Here’s how brake pads work.

Why Your Brake Pads May Be Wearing Unevenly

When you want to slow down, press the brake pedal down. This activates a cylinder that allows brake fluid to move through hoses and down to the calipers. The calipers engage your brake pads. This action causes the brake pads to apply pressure to the rotors located at each wheel. This friction is just what is needed to gain control over each wheel, slowing it down until it comes to a complete stop. Take your foot off the brake pedal, and the entire system sets up by reversing the process. 

It’s the brake pads that regulate slowing and stopping. Without brake pads, your car wouldn’t have the same level of control. If they don’t work correctly, you won’t have restraint.

Why brake pads wear unevenly 

Brake pads operate through friction. This friction occurs every time you press down on the brake pedal, causing the caliper to push the brake pad against the rotor. Rotors are fast-moving metal discs that push back against the brake pad to slow the vehicle. 

Brake pads are powerful components when you compare their size to the job they perform. No more than a few inches in width and length, their solid core is built tough to stand up to a lot of pressure. Each wheel has its own brake pad. It’s normal for front brake pads to wear at different rates than rear brake pads because the front brakes take more force from moving down the road. In theory, the brake pads work in pairs – each pair should wear in the same increments. If the left front brake pad wears differently than the right front brake pad, you have a problem.  

What causes brake pads to wear unevenly

There are several reasons brake pads wear down differently on each side. 

Guide pins – guide pins are metal pins that give the brake caliper flexibility to move back and forth with the wheels. These pins are in constant action, taking the abuse from the impact of the road. Over time, they can become dirty and corroded, which reduces their ability to move freely from side to side. When this happens, the caliper can stick in one position. It no longer is flush with the brake pad, meaning it creates small spaces between the two materials. Left unchecked and unrepaired, it impacts the functionality of the brake pad. 

Calipers – calipers push the brake pads against the rotors. If the caliper doesn’t engage properly, it can wear down the brake pads unevenly. This usually happens if the caliper doesn’t get enough pressure to the piston, or once engaged, it isn’t released in a timely manner. If the piston fires but won’t go back in, it’s a problem for the brake pads.

Rotors – rotors are small metal disks at the center of each wheel. They are more exposed than other parts, and are often subject to damage from debris on the road. Like brake pads, they are created with specific dimensions to fit snugly into the braking system. Debris can sometimes lodge between the brake pad, creating an uneven surface area. Over time, this causes deep grooves in the surface of the brake pads, and can eventually warp the rotors. 

Misalignment – sometimes, when new brake pads are installed, they are misaligned. This causes uneven wear right from the start. You should start noticing this after a few weeks or months of wear, depending on how much you drive.  

Brake lines – every time you press down on the brake pedal, brake fluid flows through the system to control the braking power. If these brake lines are clogged or damaged, they won’t provide the right brake fluid level. This means pressure will move from the caliper to the brake pad at different quantities, putting varying amounts of pressure onto the rotor as you slow and stop.  

It’s your brake pads – schedule an inspection

For most vehicles, car manufacturers recommend that you check and replace brake pads about every 50,000 miles. Of course, it depends on the make and model; your owner’s manual can provide more guidance. 

While it’s a good idea to keep mileage in mind for scheduling maintenance visits, you should also pay attention to what your car is telling you. If you notice any signs of braking problems, it’s important to get the system checked out. It’s the surest way to keep you safe. 

Brake pads have built-in sensors that alert you when they need replacing. However, with uneven brake wear, you might not reach that point before you start noticing problems. Take note of what happens when you brake, and convey that to your mechanic. They will be able to thoroughly inspect the system and make corrections, as needed.
