Why Are My Brake Pads Wearing Differently On Each Side

June 29, 2020 by admin

Let’s talk brake pads for a moment.

Your brake pads are a part of your vehicle’s braking system. Brake pads are not the same thing as brakes. Instead, they are just one piece of the entire system. However, they are one of the key components because the contact and create friction as they connect with a vehicle’s brake rotors. These are the flat, shiny disks that are often visible through your wheels.

This friction is what gives your car the ability to stop. Pressure from the brake pads on the rotors slows your car down until it eventually stops moving.

Simple, right?

The process may sound easy enough. But the concept that allows a simple piece of equipment – the brake pad – to undergo extreme conditions on a daily basis, and still carry you safely from place to place without problems is a little more complicated.

Brake pads

In the past, brake pads were often made of asbestos. The friction created between the brake pad and the rotor creates an intense amount of heat. Asbestos is a great product for absorbing that heat. The problem is, asbestos is also hazardous to your health. As brake pads wear down, brake dust begins to dissipate, with the chance of it floating through the air. That’s a dangerous thing to breathe.

Today, brake pads are created from more natural materials such as metal, rubber, glass, ceramic, Kevlar, and resin that can withstand the heat. They are sometimes referred to as organic brake pads because they are made from materials that won’t pollute as they wear down over time.

There isn’t a “one brake pad fits all.” Some are made to be softer, to help create a quieter ride. Others are made for performance, perfect for cars built for hugging the road. Knowing what type of car you drive, and the way you drive your vehicle will help determine the best brake pad for you.

Brake pads wearing differently

Over time, your brake pads will begin to wear down. As they are pressed against the rotors, they heat up. Doing this over and over again causes enough friction to remove bits and pieces from the brake pads – brake dust may often appear in your wheel wells. Eventually, it will be time to replace your brake pads.

Brake pads are the most common replacement part of your braking system. And in most cases, the brake pads will wear on each of your wheels at approximately the same pace. But what about if one of the sets of pads wears down faster than the other? What is that doing to your vehicle?

On every vehicle, you have four brake pads – a set on the front wheels, and a set on the back. Front and rear brake pads will naturally wear differently because they are designed to perform in separate ways. The forward movement of your vehicle puts more pressure on your front brakes. That means they often wear faster than the rear brakes.

However, you might occasionally notice one side wearing faster than the other. What if the driver’s side brakes are more worn down? What causes that?

It might be a problem with the brake caliper. The brake caliper is designed to push the brake pad into the rotor. Without the caliper, you wouldn’t have proper pressure between the two to slow down your vehicle. Sometimes these calipers can stick, which can push the brake pad into the rotor ever so slightly even as you drive. That means the brake pad is continuing to wear every time you go for a drive, and will wear faster than the brake pad on the other side.

It might be a problem with the rotor. Rotors are known to sometimes wear unevenly, causing a Disc Thickness Variation – DTV. This variation can be caused by a variety of things, such as the caliper sticking, dirt sticking to the pad, or even consistent slamming on the brakes.

It might be a problem with misalignment. For a brake pad to work correctly, it must be aligned in such a way so that the entire brake pad connects with the rotor when you press down on the brake pedal. If that alignment is thrown off a little, it can cause a portion of the brake pad to wear faster than the rest. Not only can brake pads wear differently on each side of the vehicle, but the brake pad itself can show different signs of wear on different portions of the pad.

You have a brake pad problem

Because brake pads are one of the most important systems on your vehicle, as brake pads wear down, they give you a variety of different warning signals.

Squeaking, squealing, grinding noises – you can’t ignore the noise of a brake pad that is reaching end of life. They are designed in such a way so that they purposely produce this noise, and will keep creating it every time you step on the brake pedal.

Slow response – have you noticed you have to press down on the brake pedal more to bring your vehicle to a stop? That’s a sign your brake pads are wearing down. It takes more force to create the same action.

Pedal feels squishy – by the same token, when you press on the brake pedal, it may have a spongy feel to it. That’s an indicator your brake pads are worn out.

Burning smell – if your brakes receive too much heat, they can take on a burning smell. That chemical odor is a sign of overheated brakes, and could be a sign they need to be replaced.

Vibrations – as you press down on the brake pedal, you might feel vibrations pulsing through your foot. It may be a sign of bad brake pads or rotors, caused by the two not connecting as they should.

You can’t change brake pads on one side

We get this question a lot. You can’t just replace one brake pad on one side of your vehicle. While it may be tempting to try and save money, keep in mind that this can be dangerous to do.

Brake pads are designed to wear evenly on both sides of your car. That means replacing both front, or both rear, at the same time.

Do you suspect uneven wear? Have you noticed your brake pads are wearing differently? Schedule a brake service check today, and we’ll ensure you’re back on the road, ready to drive safely again in no time.

Brakes 101: Does Slamming On The Brakes Hurt Your Car?

June 21, 2020 by admin

Slamming on the brakes is something we all experience from time to time.

You’re driving along, thinking about work. Or school, or the kids, or what you’re doing this weekend, or what to pick up at the store …

At any given moment, there may be a dozen things running through your brain. But all of a sudden, you look up and see the car in front of you stop. Your only option is to slam on the brakes and hold on.

Then afterward, you take a deep breath and continue on your journey. You’re okay. But is your car?

What slamming on the brakes can do

Cause an accident – the most damaging thing that can happen is you’re involved in an accident. Depending on how severe it is determines if you’ll drive away.

But even if you don’t connect with another car, you can still cause damage inside and out. If you lose control, you might swerve into a curb, damaging your wheel. The sudden forward motion can also throw your passengers around in the car. They can jerk their heads, bump windows and doors, even experience whiplash depending on the speed.

Reduce your gas mileage – when you’ve experienced a heart-pounding experience, the last thing you might think about is your gas mileage. But if you find yourself slamming on the brakes frequently, it could be a sign you’re an aggressive driver.

Following too close and tailing people means you move into reactive driving. Your decisions are always about reacting in quick bursts, depending on what the person in front of you is doing. There is no margin of error; you have to react quickly to keep your car under control.

According to the Department of Energy, aggressive driving will lower your gas mileage by as much as 15 percent in the city, and up to 40 percent on the highway. Just think how much you’ll save if you back off and take a few extra minutes to get where you’re going.

Damage your tires – when you slam on the brakes, the most obvious part on your vehicle to sustain damage is your tires. You may hear the screech as they connect with the pavement. You may see smoke pouring up from under your car. You may smell a smell of burning rubber. That can’t be good for your tires.

And it isn’t. Sudden braking can cause flat spotting.

Flat spotting occurs when your wheels lock-up and your car skids. Because one small portion of your tires stay connected with the pavement while your car skids, it can wear that section as it remains on the pavement. That uneven wear causes a flat spot on the tread. While this might not damage your tires enough for replacement, it can shorten the lifespan of your tires.

Brake pad deterioration – brake pads are designed to connect with the rotors and create friction, which brings your vehicle to a stop. While they are designed to provide this action no matter what speed you’re going, slamming on the brakes places extra pressure on the connection. And that connection can cause your braking system to overheat.

As the braking system overheats, it can cause the brake pads to wear down faster, and allow stress to be placed on the rotors that may compromise the entire system. Even one incident of slamming on the brakes can put your entire braking system at risk, especially if your brake pads or rotors were already compromised.

How do you know if sudden stopping caused problems within your braking system? Pay attention to how your car drives. Do you have a shaky steering wheel, hear a squeaky sound as you apply the brakes again, or notice a brake light on your dashboard? All can be a sign that your braking system received more damage than you thought.

Damage to brake hoses – it’s not just the brake pads that can be impacted by a quick stop. As you push the brake pedal to the floor, brake fluid moves through the system, providing the pressure needed to bring the car to a stop.

The quick-action creates heat and pressure to move through the entire brake system, which can begin to cause damage to every part within the system. Small cracks and leaks can begin, especially if the hoses are old and were already internally weak.

Immediately following a quick stop, watch your vehicle carefully for a few days. Check under the car as you drive away – are there signs of brake fluid? Does your brake light flicker or turn on your dashboard? Watch for signs and contact one of our mechanics immediately to reduce the chances of further damage to your car.

Damage to the driveshaft – the drive shaft is what connects the engine to the wheels. This is what gives your vehicle the power to move and turn.

Think of the drive shaft as a “ball and socket” structure that allows movement and rotation. When you stop quickly, it can dislocate this structure, causing the joint to be slightly off askew.

Will your vehicle continue to drive? Possibly. Your car might not show any external damage. But over time, if this joint doesn’t perfectly mesh, it can begin to wear down and cause damage elsewhere in your car.

What you can do to prevent brake damage

It doesn’t take a rocket scientist to know that even small amounts of damage can cause your car to wear faster, and possibly be not as safe as it was when you drove off the lot.

Keeping your vehicle in good condition means you’ll get a longer life from it, as well as keep the occupants safer everywhere you drive.

Slamming on your brakes is an easy problem to solve. Yes, we all might have to do it from time to time. But if you find it’s a normal part of your commute, it’s telling you to tone down the aggressive driving behavior.

Be more aware of how you drive. Notice hazards that you meet regularly and do what you can to avoid being placed in those situations. Leave a few minutes earlier, no matter where you’re off to, and give yourself more time to get where you’re going.

You’ll enjoy the ride more. And your car will love you for it too.

What Your Parking Brake Is For

June 14, 2020 by admin

There are a lot of parts to a car that we tend to take for granted. They’re there. We may use them from time to time. But we rarely think much about them.

That defines the parking brake perfectly.

The parking brake is designed for what its name suggests: to add extra security to your vehicle when it’s stopped, resting, and you’re away from the car. Of course, that’s not it’s only function. Which is why it is sometimes referred to as an emergency brake, e-brake, or hand brake too.

When you think parking brake, think safety. That’s what it’s designed for. But what is its true function?

Let’s start at the beginning.

How does a parking brake work?

A parking brake is a part of a car’s braking system. It connects to the rear brakes, and when engaged, engages the vehicle’s primary braking system with less force.

Looking back at history, the parking brake was an important part of the braking system. It was designed to give a driver another option to stop the car if, by chance, the hydraulic brakes fail while driving.

On modern cars, however, the parking brake is rarely needed in that circumstance. That could be why the name has morphed over time from the emergency brake to the parking brake.

While your primary brakes operate through a technology-driven hydraulic system that gradually brings your car to a stop, the parking brake is designed to hold your car in place.

Today, we use the parking brake as an extra precaution for keeping our vehicles motionless while parked. This can be a big benefit when parked on steep inclines or declines.

As our vehicles get more sophisticated, the way systems operate is changing too. In general, there are four different types of parking brake systems. You can check your owner’s manual to confirm what comes equipped on your vehicle.

Stick lever – on older cars, you’ll find this located on the instrument panel
Center console lever – this is located between the two front seats
Foot pedal – this is located on the floor on the left side of the pedals
Push button – with newer cars, you’ll find the parking brake can be activated by a button located somewhere on the console

When should you use your parking brake?

As the name implies, a parking brake should be used whenever you park your car. Whether you drive with manual or automatic transmission, the parking brake adds extra security when you walk away from your car.

While some will tell you that parking brakes are more important when you park on an incline or decline, others will tell you it’s equally important to use it no matter where you place your vehicle. Your braking system uses a device that keeps your brakes locked and engaged whenever you put your car into park and walk away. However, failure can occur, and it’s not just the brakes that can cause the problem. If the gears aren’t engaged, it can cause your car to roll, even on what appears to be a flat surface. Engaging it each and every time you turn off your car ensures your car stays where you place it.

Here’s a tip for reducing the stress on the drive train. If you are parking on an incline or decline, leave your foot on the brake pedal as you move the gears to park position. Before you take your foot off the brake pedal, engage the parking brake too.

Have you ever let your foot off before engaging the parking brake? Have you felt your car jolt forward or backward as it adjusts to sitting on an incline? That action over time can damage both your transmission and braking systems. That means costly repairs before their time. Engaging the parking brake first prevents this action from occurring, protecting various systems throughout your vehicle.

When you’re ready to drive, start your engine, press down on the brake pedal to engage the brake system, release the parking brake, and then move into drive. Driving with your parking brake on can damage your vehicle.

Why is a parking brake important?

Get into the habit of using your parking brake every time you stop. It gives you added stability while your vehicle is inactive. While this can be important to keep your vehicle stable while resting on an incline, there are other circumstances where this is important too.

For example, if you’re sitting on a busy street or in a parking lot, and someone hits your vehicle, the parking brake decreases the chance of it rolling, increasing the likelihood of damage.

It also keeps your car in overall good working condition. If you don’t use parts, they start to wear. A parking brake that is rarely used can stiffen, rust, corrode, weaken, and wear down, meaning it’s less likely to work when you need it most.

Like every part of your car, it’s important to have the parking brake regularly inspected to ensure it’s in proper working condition.

Potential problems with your parking brake

While parking brakes rarely present problems, you may likely find yourself in one of these situations:

Parking brake frozen – ice can cause the parking brake to freeze when it’s really cold. Leaving the engine run for a few moments can start to heat your car and make the ice melt. If this doesn’t melt it, you can find which wheel it’s connected to, and melt the ice with a hairdryer.

Rust or corrosion – over time, corrosion or rust can infiltrate the mechanism inside the parking brake, making it harder to work until it freezes altogether. It might be difficult to diagnose without having it towed in. You can apply and release the brakes a few times to see if you can disengage it. Shift between reverse and drive to see if it loosens up the debris enough to take the parking brake off. If not, your only choice is to have it towed and repaired.

Engaged too hard – when people are in a hurry, they often make quick movements that can hurt more than help. That’s often the case with the parking brake. If you pull up too hard, it can jam it. Pulling with all your strength can get the brake shoe stuck in the wheel drum. It can stretch out the cable that runs from the wheel to the brake handle enough that makes it impossible to disengage. If you’ve tried and can’t release the parking brake, it may be time to seek help.

Whether you have a question about a specific problem, or just need an inspection and check up to keep you on the road safely, we can help.

Help! My Brakes Smell Like They’re Burning

June 10, 2020 by admin

Ah, a new car smell. Just saying it brings thoughts to mind.

How would you describe it? While it may be difficult to put into words, what you might not know is all the time and energy put into creating it. Yes, people really do pay attention to the way a new car smells.

While you can argue how natural those smells really are, the good news is they fade away. Drive it around for a short time, and your car will no longer smell. (At least a new car smell. If you leave a gym bag behind the seat for too long, all bets are off.)

But what about when you do notice something out of the ordinary? A smell that you can’t quite put your finger on, but you know it shouldn’t be there?

There’s nothing like the smell of burning brakes. Any time you get a whiff of a burning smell while driving your car, it’s cause for concern. Safety is your top concern.

Pull over. Assess the problem.

Depending on what’s causing the smell and what you were doing when the smell first started, different courses of action can be needed.

You have new brakes

When was the last time you had your brakes serviced? When were your brakes last replaced? If you have new parts on your braking system, it could be causing the burning smell. And that’s okay.

New brake pads are covered in resin. As your brake pads adjust and settle into the braking system, the material starts to burn off. This smell is a sign your brake system is working, getting stronger each time you work them.

This break-in period is different for every vehicle, for every set of brakes. With some, you may not notice it at all. With others, it can linger for days.

Give it a few days. You should start to sense the scent disappearing. If it’s still strong days later, bring it back in and one of our mechanics will check it out.

Your parking brake may be engaged

The parking brake is a system that some drivers use all the time, others, not so much. If you fall into the “once in a while” group, you might accidentally leave it engaged.

If you notice a burning smell soon after you start driving, check to ensure your parking brake isn’t engaged. The friction caused by driving while the parking brake is on can overheat over time, eventually causing damage.

Of course, the burning smell is only part of what you might sense. Other indications include trouble accelerating, a squealing noise, or even the sound of grinding. On some vehicles, you might even have a light emit on your dashboard panel.

Double check that the parking brake is off, to rule this out as a possible cause of the burning smell.

Your brakes are overheating

The third and most serious of potential problems is if your brakes are overheating.

Every time you use the brakes on your vehicle, they work by creating friction to slow down or come to a stop. While brake pads are designed to take normal wear, if you drive aggressively or overuse them, it can lead to your brakes overheating.

We see it quite regularly because of the Rocky Mountains. If you head up into the hills regularly, it can happen if you ride the brakes coming back down. Friction causes heat. By leaving the brake pads engaged for minutes at a time, the heat builds to a point where it overheats. That’s when the burning smell starts. Some people say it smells like carpet burning. In any case, it’s a scent you’ll pick up on immediately, and one you should pay attention to for safety.

The smell might be the first indication, but there are usually more. You may notice the brake pedal feeling a little spongy when you press down on it. You might notice a stream of smoke coming from under the car.

Your first course of action is to get to safety and stop. Give your brakes a chance to cool down while you consider your next actions.

How to avoid overheating

Especially here in Colorado, it’s important to have other ways to control your vehicle.

First, drive cautiously, not aggressively, leaving plenty of space all around you. If you’re not following close behind another car, you’ll have more opportunity to apply light pressure instead of pouncing on the brake pedal. It’ll also prevent you from riding the brakes, using them consistently throughout your drive.

Next, try downshifting instead. Even automatic engines have multiple gears for this reason. Instead of riding the brakes, especially coming down a steep hill, downshift and let the engine do the work instead.

Finally, have a mechanic as a friend. If you schedule regular checkups for your vehicle, you’ll stay on top of potential problems. You’ll learn if your brakes are wearing down, or discover how much tread is left on your tires. You’ll take the guesswork out of staying on top of what work needs to be done to your car.

Is it all brake pads? Can it be just one?

It’s also important to keep in mind that brake pads can sometimes wear at different levels. Your front end and read brake pads naturally will wear differently.

Even then, as your vehicle is moving forward, this momentum tends to put more strain on the front brakes. This often causes them to wear quicker than the rear brakes.

However, you’ll sometimes find brakes wearing on one side more than the other.

It’s the brake caliper’s job to push brake pads against the rotors. This is what creates the friction, causing your vehicle to stop. If the caliper sticks, meaning it stays pressed against the rotor, it will wear faster than usual.

Sometimes rotors wear unevenly, which is known as disc thickness variation. It can wear due to sticking calipers, or dirt getting trapped between the pad and the rotor. Pouncing on the brake pedal frequently can also cause a problem.

It might even be a misalignment in the brake pads. If they bounce, or simply not installed right, it can also lead to problems.

Take action – have your brake system checked

Smells are designed to give you advance warning of a problem.

If you notice a distinct smell to alert you to burning brakes, safety is your first concern. Give us a call soon after. We can get your car in, make necessary repairs, and have you back on the road again in no time.

Driving With ABS Brakes

March 16, 2020 by admin

Do you know what kind of braking system you have on your vehicle? It matters. Do you think you should pump your brakes to get them to stop better on a slippery surface? Or are they computerized and they pump the brakes for you?

The most common brakes on today’s vehicles are anti-lock braking systems, or ABS for short. They employ a computer and sensors in the wheels to give you a big edge over the older systems. ABS began to be regularly installed on vehicles in the 1970’s but weren’t mandated until 2004 in the European Union and 2013 in the United States.

Let’s go back to the “old” days when there were no computerized brakes. The driver pushed down the pedal that then sent pressure to all four wheels at the same time. Unfortunately, all four tires aren’t gripping the road the same way; some have more traction than others because of the varying road surface, so stopping and steering can be compromised. In older systems, pumping the pedal made sense because a driver was letting off the brakes when the tires were skidding in an attempt to regain traction.

ABS changed all that. Sensors in each wheel now can determine which ones are turning faster than others and then adjust brake pressure accordingly, maintaining maximum grip. They automatically “pump the brakes” up to 20 times a second. That helps a driver’s stopping distance and steering control, both important in avoiding obstacles.

ABS is designed for the driver to apply steady pressure on the pedal since the computer can do things that are not humanly possible. If you have ABS, pumping the brakes can defeat the technology that’s trying to help you maintain control. Remember the three S’s: Stomp-Stay-Steer. Stomp your brakes, stay on the brakes, and steer as needed.

Now you can see how important it is to know which system is in your vehicle. If you’re not sure, consult your service adviser. That’s also a good time to go over your vehicle’s brake system and maintenance schedule. ABS is sophisticated technology and needs to be maintained so it will work the way it is designed. Remember stopping and going are both important when it comes to vehicle safety.

A Guide To Anti-Lock Brakes

February 10, 2020 by admin

If you’ve ever driven an older car, stomped on the brake pedal, trying to get the car to stop quickly, only to feel the cart slide and swerve, you know how scary it can be not to have full control over your vehicle. ABS – anti-lock braking system – is designed to give you more control in more situations.

The concept of anti-lock brakes actually started almost 100 years ago. Engineers were looking for an override system for aircraft, and ABS technology became the standard to prevent the wheels from sticking as the plane rapidly decelerated.

In the 1950s, ABS technology moved to motorcycles to improve safety and handling. And slowly, it was introduced into vehicles over the course of the next few decades. By the 1990s, anti-lock brakes were standard issue on most production line vehicles.

How do anti-lock brakes work?

Let’s talk a bit about how anti-lock brakes work. If you think back to your lessons in drivers ed, you might remember how they taught you to take control over your car if you hit a patch of ice. If the brakes won’t work and you slide, pump the brakes instead by pressing down on the brake pedal and letting go, over and over again. This helps your tires look for traction instead of continuing to slide.

That same concept explains how ABS is designed to work. If you suddenly want to come to a stop and apply a lot of pressure to fast-moving wheels, that intense pressure can cause your wheels to lockup. This will typically cause them to lose traction, and you’ll slide and skid uncontrollably.

ABS is designed to prevent this. Anti-lock brakes use sensors to determine the motion of your wheels. When you press down on the brake pedal, these sensors activate and monitor the wheel movement to determine the action. If it senses lockup, it turns on the ABS, which pumps your brakes instead of locking them up. The timing of it occurs with precision, thanks to technology, a vast improvement over what you could do simply by tapping your brake pedal over and over again.

Why are my anti-lock brakes coming on?

Your vehicle is technology-driven, with every part working together to keep you safe. Every new year brings new technology to light, meaning if you have the latest production car, technically, it will have the safest features on the market.

If you’ve ever stepped on your brake pedal and had the ABS turn on, you might have felt a vibration. Depending on your car, you may have a small dashboard light turn on as well, telling you your anti-lock brake system has been activated.

Based on road conditions, the vehicle’s technology has determined it needs ABS to keep the car safe. In some cases, the pulsing of the brake system may not stop the car as quickly as it normally does. But it has determined that this action is better to bring your car to a stop, and risk sliding or skidding out of control.

Where is the anti-lock brake?

The good news is most new cars on the road today have anti-lock brakes. If you’re driving an older car or truck and wish to determine if you have ABS, there are several ways you can go about it.

The easiest is to check your owner’s manual.

If you don’t have access to your owner’s manual, you can check your dashboard instrument panel. As you turn your car on, yet before you turn it to start, all lights will flash on. Think of this as “test” mode. If your car has ABS, it will be illuminated at this time. Look for a light that either says “anti-lock” or “ABS.”

If you have a basic understanding of the parts of the car, you can also pop the hood and take a look inside. The anti-lock brake pump will sit near the brake master cylinder, and be connected to several different lines.

The final way is to physically look at the setup of the wheel. You’ll have to get into position to be able to see the brakes on the front wheels. If your car has anti-lock brakes, you’ll see a flexible hose attached to the brake caliper, with a wire attached to a speed sensor in the hub of the wheel. This sensor will be missing if your car doesn’t have ABS.

How do you test anti-lock brakes?

The best way to ensure your anti-lock brakes are working is to check that the warning light illuminates on your dashboard during test mode every time you turn your vehicle on. If you don’t see the icon light up, it’s best to let your mechanic check it out and ensure everything is working correctly.

Likewise, if your ABS light turns on at any point while you’re driving your vehicle, schedule a maintenance visit as soon as possible to ensure your braking system is working the way it should.

How long do ABS controls last?

ABS is designed to work in all kinds of conditions, and be there for you no matter when you need it. It’s not something you turn on, or that you have to change out the fluid for on a regular basis. But like any other part, it can wear out over time.

As anti-lock brakes initiate, you’ll feel a slight pulsating mechanism underneath your foot. It clicks, and then it creates rise and fall in the system, which you can feel by having your foot on the brake pedal. This is known as the ABS control module.

The brakes are one of the essential systems in your vehicle. You use them every day, dozens of times, as you move in and out of traffic to accomplish all you do on your drive. The anti-lock brake system is separate from your brakes. That means even if the ABS fails, you’ll still have your braking system to rely on.

Under most conditions, ABS will last the life of your car. But because it is electronic, it can suffer from several things, including an electrical overload, or overheating due to high temperatures. If the ABS light comes on, one of our professional mechanics will replace the control panel.

Is your ABS working correctly? Is your braking system keeping you safe? We can ensure everything on your vehicle is working correctly, to ensure the safety of you and your family.

Brake Fluid Low? This Is How You Know

February 7, 2020 by admin

What happens when you push down on the brake pedal?

Your car slows and eventually comes to a stop.

Touch it lightly, and it slows just a bit. Stomp on it, and you can stop in mere seconds. According to the National Association Of City Transportation Officials, the average vehicle going 60 mph will come to a resting point in 4.4 seconds. You’ll feel that motion if you stop at that rate, but it can be done.

However, the only way that can happen is if your braking system is working the way it should.

How the brake system works

Brakes are actually pretty straightforward in the way they operate. We’ve written about it here and here. But for the sake of this article, we’ll condense it into one paragraph format.

When you press down on the brake pedal, it pushes an internal lever that increases the pushing force. This lever pushes a piston into a cylinder filled with hydraulic fluid, also known as brake fluid. The fluid condenses and squeezes out through the end, down a pipe until it reaches another cylinder located at the wheel. Here, it pushes another piston with increased force. It connects with the brake pad and pushes it towards the brake disc. As the brake pad touches the brake disc, friction between the two heats, causing the outer wheel and tire to slow and eventually stop.

This basic principle happens four times over, for every line to every wheel on your car.

What makes it all possible is the brake fluid. It’s what increases the pressure to the point of making the mechanics of the braking system work.

It’s time to check your brake fluid levels

You’re already in the habit of checking your motor oil on a regular basis. Low brake fluid is equally important. Yet keep in mind that brake fluid doesn’t need to be changed out as frequently as motor oil, nor is it as vulnerable as the oil used to keep your engine running clean.

However, brake fluid is a vital fluid needed to keep your car running smoothly. It can be the difference of being able to stop your car whenever you desire, or not.

Like your motor oil, checking your brake fluid should be a part of your regular maintenance plan. Especially if you notice your brakes not behaving as they should. Do your brakes feel spongy when you press down on the brake pedal? It’s time to check your brakes. Do you hear a squeal as you tap on the brakes? It’s definitely time for a check up.

Like motor oil, brake fluid can have a variety of things wrong with it. If it’s low, there might be a leak somewhere in the system. If it’s contaminated, it means dirt and grime has found a way inside.

Brake fluid impacts every part of the braking system, the brake pads, rotors, calipers, and brake lines. And if the brake fluid doesn’t have the proper makeup, chances are it’s impacting any or all of these parts in various ways. A thorough inspection is needed to ensure your brakes are working the way they should.

Finding the brake fluid reservoir

Keep in mind that filling your brake fluid reservoir isn’t like topping up your motor oil. You can’t run to your local auto parts store and buy just any brake fluid sitting on the shelf. It takes knowledge to ensure you’re purchasing the right product, and skill to fully clean the system as you change it out. Still, having a general understanding can make you a more well informed driver and car owner.

The brake fluid reservoir is typically a plastic canister that is mounted near the rear of the engine compartment. It’s usually near the driver’s side brake booster. If you can’t find it, consult your owner’s manual or do a search online for your make and model. It will point you in the right direction.

Most newer vehicles use a translucent plastic with a fill line, so you can immediately tell if the brake fluid is low. Older vehicles might have a metal reservoir, with a clamp securing the top into place. Different vehicles have different rules about opening up the lid. Follow guidelines exactly or risk contaminating the brake fluid. Exposure to moist air can contaminate the fluid in just a few minutes, so it’s important to know what you’re doing before you open it up.

Brake fluid looks okay if …

The first check is to ensure you have enough brake fluid in the system. Does the brake fluid levels reach the fill line?

If it doesn’t, that can be a warning sign your brake pads are wearing thin. This is because as brake pads wear down, they take more action to work. The piston will need to move farther into the system, requiring more fluid to complete the process.

If the fluid level looks okay, the second step is to inspect the fluid itself. Brake fluid is normally a clear or light gold color. If it turns brown or black, the brake fluid is contaminated and it needs to be replaced. As dirt enters the system, it slowly changes the coloring, giving the fluid its darker appearance. It allows dirt and other contaminants into the braking system, which in turn can damage other parts.

Adding brake fluid

As a general rule, you should have your brake fluid replaced about every two years. Of course, this depends on a variety of things, including your drive style, the make and model of your car. Check your owner’s manual for recommended guidelines. One of our experienced mechanics can also provide you with more information.

Different vehicles require different brake fluid. You can’t mix and match. If you use an incorrect formula, or overfill your brake fluid reservoir, you risk having your brakes working incorrectly. Most systems use either DOT3 or DOT4 brake fluid. Consult your owner’s manual, or find the information located on the brake fluid reservoir cap.

Brake fluid is toxic and highly corrosive, so proper protection is needed anytime you deal with brake fluid.

Once brake fluid is changed, it also requires testing and bleeding the brakes.

The Most Common Automotive Brake Problems

September 18, 2019 by admin

What’s one of the most critical systems in your car? It would be hard to argue against the braking system. Imagine your brakes failing as you’re exiting the highway, or as you’re slowing down to round a corner.

Which is why it’s important to pay attention to the little things your car tries to tell you every time you drive. Many common automotive brake problems can be solved quickly – if you catch them early enough. The more you listen to what your vehicle is telling you, the safer you’ll be.

How to stop

The art of stopping is based on kinetic energy. Every object on earth has kinetic energy based on its mass and velocity. The object’s mass (weight) determines its velocity (how fast it will go).

To stop, you have to remove the kinetic energy. For you and me, we simply slow down our speed. But for large objects – cars – the braking system is built for the process.

Take a moment to look through your front wheel, you can see a metal disc just inside. Most cars today use what’s called a disc brake system. As you apply pressure to the brake pedal inside your car, a brake pad clamps onto this disc and rubs it to stop the motion. It slows it down depending on the force you apply to the brake action.

Cars not only have a lot of weight, but they can also reach very high speeds. Have you ever hit 70, 80, or more on the highway? Your brakes have to be able to stop quickly even at these speeds without throwing your vehicle into a tailspin. When you hit the brake pedal, all of this energy is immediately transferred to the brake pads. That means these pads have to be able to withstand a lot of heat (950 degrees F or more) and be able to function properly.

For that reason, brake pads are made of materials that won’t melt, such as alloy, ceramics, or other carbon-based materials. Eventually, these pads start to wear down. The thinner they get, the more pressure you have to apply to perform the same function. Until eventually they wear out altogether.

You want to get a full lifespan from the brake pads. You have to parallel that with replacing them before they put you at risk. That’s why it’s important to have a mechanic on your side, who will provide you with honest, accurate feedback on what to expect from your investment.

A lot happens in between installing new brakes and replacing them when they’re worn out. Here are a few things to keep in mind.

What is brake dust, and what causes it?

Have you ever washed your car and noticed gray-black dust covering your wheels? That’s brake dust.

As the brake pads apply pressure to the disc, iron particles slowly grind off. These small iron and metal particles are nothing more than residue from the brake pad material as this process occurs.

Brake dust is not an indication that your brake pads are malfunctioning. Yet it is important to clean brake dust away from your wheels, as it can erode the clear coat of your alloy wheel, which causes more problems to your vehicle.

Fortunately, that’s an easy process. You can purchase wheel cleaner at your local automotive shop. Just use a soft bristle brush and rinse it away.

What is brake fade?

Have you ever pressed down on the brake pedal and it’s felt like the brakes aren’t working? It could be brake fade. There are several reasons this could be happening.

Friction fade occurs when you overuse your brakes. This happens quite frequently here in Colorado because of the Rocky Mountains. As you’re coming down a steep hill, to keep the car from gaining speed, some unsuspecting drivers will put their foot on the brake pedal and keep applying pressure. That constant friction creates enormous amounts of heat. This can cause the brake pad and rotor to stop working.

Older cars might experience brake fluid fade, which is caused by a degradation of brake fluid. Different manufacturers have different requirements on when to replace your brake fluid. If you ignore these guidelines, it begins to absorb water and other debris. That causes the brake fluid to boil at lower temperatures, causing steam to build up in the system. If you’ve ever felt your brakes getting a little “spongy”, this is the cause.

While not one of the most common reasons for brake fading, you can occasionally experience mechanical fade. New brake pads have a resin in them that can break down as it heats. If they weren’t created properly, it may produce a gas that prevents friction between the pad and the disc. This causes the brakes to stop working.

If you experience any of these, it’s important to allow your brakes to cool down. Pull over to the side of the road and give them time to cool. If you’re coming out of the mountains, downshift to lower gears to take the pressure off the brake pads. Do not touch any part of the wheels or brakes – they will be very hot to the touch.

What if my car shakes or has vibrations?

Another common automotive brake problem leaves your vehicle shaking or vibrating.

Have you ever noticed your steering wheel shaking? It could your brake pads are contaminated with dirt, oil, or other substances. It can also occur if your brake pads are warped, damaged, or excessively worn.

It could be your brake disc or rotors are worn down. As the surfaces continue to function and take heat as you brake, they sometimes wear in different ways. That can cause unevenness over the surface areas. When you apply the brakes, the brake pads grab the discs unevenly, and you’ll feel a vibration as you come to a stop.

It could be alignment issues. If your car has experienced damage from potholes, for example, it can impact the way the entire suspension system works. If you feel vibration in the pedal as you press down, it most likely has to do with your alignment.

Lastly, the more wear your entire suspension system has, the more parts could malfunction. Ball joints, wheel bearings, tie rods – there are many possibilities. This is when it’s important to notice when you have most of your problems. If you notice it primarily during turning, it’s your suspension system. If it’s primarily when you brake, it’s your brake pads or rotors.

Is it time for brake repair?

Have you noticed any of these common automotive brake problems with your vehicle? Maybe it’s time to have a mechanic thoroughly evaluate your car.

What Happens If Your Brakes Overheat?

August 8, 2019 by admin

Our modern society can’t survive without driving a car. Eighty-three percent of all Americans drive on a frequent basis.

Here in Colorado, it’s more than a choice; it’s a necessity. If you want to get to work, school, and enjoy your free time a little bit more, owning a car can get you where you’re going in a fraction of the time.

Of course, owning a car means certain responsibilities. If you own a car, you have to maintain it, so it becomes reliable whenever you need it. What Happens If Your Brakes Overheat?

Have you noticed the brakes squealing? Or maybe you notice a new smell as your brakes heat up. All of these and more may be a sign that you have a problem with your brakes.

What happens when you brake?

Most people assume it’s the brakes that stop your car. That isn’t the case. Instead, the brakes are designed to stop the wheels from moving. It’s your wheels slowing down that stops the car.

Modern disc brakes are a large plate-sized disc attached to each wheel. The clamping of the discs causes friction. This is what slows you down. But this friction also generates heat, and that heat has to go somewhere. Disc brakes are designed to dissipate the heat in different ways. Heat will transfer to the brake pads and the brake fluid. It may have a ventilated core with air ducts that help keep them cool.

The system is designed to work flawlessly … for a while. But like everything, sometimes things don’t happen the way they are intended.

What happens if brakes overheat?

When you push down on the brake pedal inside your car, your vehicle’s brake pads generate friction. This friction is what slows the car down or brings it to a stop, depending on the level of force.

This action occurs over and over again as you move through the city. But sometimes as heat builds, there’s too much of it. How do you know if your brakes are overheating?

Your brake pedal feels soft

This is where it helps to pay attention to how your car handles. When you press down on the brake pedal, does it have a “spongy” feel? Over time, water can start accumulating in your car’s brake fluid reservoir. As that heats up from use, it starts to reduce the effectiveness of your brakes. This isn’t always a sign of brakes overheating; it could be several other things. Like damage to the brake line. Or low brake fluid. No matter what the problem, if you notice this “soft” feeling when you tap the brake pedal, it’s best to come in for inspection quickly to avoid the consequences of brake failure.

Your brake pads smoke and smell

Instead of feeling a problem, you may see or smell it instead. Do you notice smoke coming from the wheels? Or maybe you notice a smell every time you brake? This is your brake system telling you something is wrong.

When brake pads overheat, they put off a similar scent to burning carpet. Once you smell it, you’ll recognize it every time. This is a sure sign that it’s time for a checkup.

Your brakes are squealing

You can also hear when brakes are failing. They often make a lot of noise. When the friction from the brake action generates enough heat, the pads start to wear and smooth. As they wear down, the glaze on the pad has more difficulty creating the friction. If you’ve ever thought it sounds like metal on metal, that’s literally the case. Press down on the brake pedal, and you’ll hear it squeak and squeal. That’s a sign it’s time to head in for an inspection.

What to do when brakes overheat

Because there are many signs of brake failure, think of it as your car’s early warning signs. It’s telling you there’s a big problem; you need to slow down and find a safe place to pull over. Only when you’re in a safe place should you let your brakes cool down and determine if they are safe to drive or you should call for a tow.

Are there ways to avoid overheating?

While overheating often comes with age, there are other factors that can make it more of a possibility.

The way you drive

Are you the type who pounds on the brake pedal? Do you roar up to the car in front of you and constantly ride the brakes? You’re more likely to experience overheating. By making your ride smooth and steady, you’ll use your brake pads in a more appropriate manner. You’ll give your brake pads a chance to cool in between your stops and starts.

The way you use your car

Here in Denver, we have a relatively flat city driving experience. But that changes the moment you head up into the hills. As you drive back down from a weekend of playing, try engine braking instead of riding your brakes. Engine braking means downshifting to let the engine take over the slowing process. This means you won’t have to leave your foot on the brake pedal as you spend minutes – hours – coming down out of the mountains.

The way you maintain your car

There are two ways to approach vehicle maintenance: routine or emergency. Either way, we’re here for you. Routine maintenance allows you to take charge of how well your car operates. We’ll check everything out on a routine basis to ensure it’s working in its best condition. Emergency maintenance means we’ll replace the brake system after you experience some type of failure. Of course, this isn’t the most desired way, as you never know when that will occur. But in the event something happens, we’re here.

What happens if your brakes overheat? Your first course of action is to stop and get to safety. But how you proceed depends on your situation.

We suggest bringing your car in and having a full inspection. Your braking system is one of the most important systems on your vehicle; let’s ensure it’s working safely.

Car Brakes 101: How They Work and How To Repair Them

August 5, 2019 by admin

What’s the most overlooked part of your car? Yep, it’s your car brakes.

You enjoy taking your car to the carwash and driving a sparkling car. You have a little sticker on your windshield, reminding you of the need for oil changes. But car brakes? When was the last time you gave them any thought at all?

Yet they aren’t something you can ignore. Car Brakes 101: How They Work and How To Repair Them

What brakes do

Brakes don’t stop the car. Instead, brakes stop the wheels from turning, which in turn slows down the car and brings it to a stop.

Most modern cars use disc brakes for the stopping process. Disc brakes consist of:

Brake discs
Calipers
Brake pads
Brake lines
Brake master cylinder

Every wheel has a plate-like disc attached to it. Also called a rotor, this plate is squeezed by the brake pads within the caliper every time you want to slow down.

Brake pads have two layers: a metal backing and a high-friction material molded onto the backing plate with heat and pressure. It’s also coated with an adhesive that helps the brake pad and caliper withstand high temperatures and excessive heat buildup.

What are brake pads made out of?

If you head back in time, the original brake pads that grew in popularity during the 1950s and 1960s were made from asbestos. It was thought to be a great material because of its heat-resistance and durability qualities. However, as health ramifications were discovered, auto manufacturers looked for alternatives to make a safer product.

The organic brake pad was created from a variety of materials and fibers and mixed together with binding resins to hold them together. You might find glass, rubber, carbon, Kevlar, and other fibers mixed in. Because they are inexpensive to create, the majority of new cars are still installed with organic brake pads today. They’re easy on the brake rotors, suitable for all driving environments, and don’t require a lot of heat to generate good friction. That makes them the perfect choice in most conditions.

The metallic brake pads are manufactured with steel, iron, copper, or other metals, added to friction modifiers and fillers to create the final product. Metallic brake pads are thought to be one of the most versatile on the marketplace, being more durable and longer lasting than the organic composition.

You’ll find better braking performance, a wider operating range in heat and cold conditions, a firmer feel in driving conditions, and more resistant in the long term. But because the brake pad is created from metal, it is noisier than other brake choices, and will produce more brake dust.

The newest brake pad on the market is made from ceramic. Ceramic pads are created from a dense ceramic material – think pottery – with copper fibers added during production. They are quieter than metallic brake pads, and produce a finer brake dust which won’t stick to wheels. And because it has the longest lifespan of any brake pad, they can be a great choice if you’re investing in your car for the long term.

What causes brake pads to wear

The biggest enemy to a brake pad is heat. As the brake pad moves against the brake disc, friction occurs, and heat is produced. To remove this heat, a car is designed with several systems to prevent buildup, especially in the front brakes where more action occurs. The brake disc is ventilated to allow cooler air to be pumped in and spread to the outer edges of the disc. The more hot air is kept away from the center, the less likely the disc will “fade.”

Fading is when brakes overheat. If car brakes are continually used while overheated, brake fluid can impact the calipers, which reduces the ability to brake. You may notice this if:

You’ve had to depress the brake pedal farther to the floor

You’ve pushed the brake pedal all the way to the floor without any braking

It takes you more distance to come to a stop

You smell a burning odor during the braking process

Your brakes start smoking or catch fire

This is where higher performing brake pads come into play. While an organic brake pad will provide excellent performance in standard conditions, only you can decide how you drive. If you need better performance, talk with one of our technicians about which option is best for you.

Keep your brake system happy

While it might be a glamorous purchase, brake pads are vitally important to your car’s safety and performance. Of course, so is regular maintenance.

Like an oil change, your brake fluid should be changed regularly too. Brake fluid attracts moisture. And moisture isn’t a good thing for your car’s braking performance.

Moisture reduces brake fluid’s boiling point, which makes it easier for brakes to overheat, especially in summer conditions.

Boiling brake fluid also enhances fading, which means your brakes can fail at the most inopportune time, like driving down long hills. That can be a big problem if you’re coming home after a fun-filled weekend in the mountains.

Moisture also corrodes metal. And since your brake pads are created from metal, it can wear down or even cause your brake pads to cease long before you anticipate.

Your best bet is to replace your brake fluid on a regular basis, according to your car’s manufacturer recommendations, or every couple of years. It’s the perfect way to keep your car happy and running well no matter what type of driving you do.

While brakes may not be the sexiest piece of equipment on your vehicle, they are one of the most important. If you want to keep a well-maintained car ready for all sorts of driving conditions, the best place to start is at the bottom – with your car brakes. Well-maintained car brakes will have better braking capability and keep you and your car’s occupants safe and secure.

And that can be a very good thing, whether you’re driving home from a day of skiing, or heading to work in the middle of the summer. Make the right choice, and your car brakes will be happy for the life of your car.
