How Do I Know If My Brake Rotors Are Bad?

by

A faulty brake system is never good. While many drivers are clued into listening for a high-pitched squealing noise, indicating their brake pads have come to the end of their lives, it’s more difficult to pinpoint brake rotor problems. When brake rotors are bad, they have several distinctive ways of telling you they are in need of replacement. 

What are brake rotors?

If you peer into your wheels, you’ll notice circular discs connected to each wheel. These are your brake rotors. Rotors are designed to turn motion into heat. They transfer kinetic energy into thermal energy to ensure safe braking. As you press down on the brake pedal, it sends a signal to the master cylinder, to the brake calipers, causing the brake pads to press together against the surface of the brake rotor. This friction resists the spinning wheel, which slows the rotation, eventually bringing the vehicle to a halt. 

Different types of brake rotors

Just like there are different types of vehicles, so are there several different types of brake rotors. This isn’t a one-size-fits-all component. Check with your owner’s manual to determine what’s right for your vehicle. 

Depending on what vehicle you drive, you’ll have one of four primary brake rotors on the market today. 

Blank & Smooth – these are the most common rotors for passenger vehicles. They are simple in design and affordable. However, as automotive practices change, some of these rotors may be created from recycled materials, meaning they don’t perform as well or last as long as other rotors. Typically they have a longer life because of a thicker material and internal fins, which allow them to cool brake pads more efficiently. You’ll notice the smooth, blank metal surface area if it uses this rotor. 

Drilled – drilled rotors have slots positioned around the exterior rotor surface instead of holes. These holes provide heat loss as well as allow dust and water to escape the rotor’s surface without clogging or blocking the entire braking system. Drilled rotors are more common in wet climates where they can aid drivers in keeping control over their vehicles on wet roads. They won’t last as long in high heat situations. 

How Do I Know If My Brake Rotors Are Bad?

Slotted – slotted rotors have slots positioned around the exterior of the rotors. They are most often used in heavy-duty trucks and SUVs, as these vehicles typically require more stopping power. They may also be used on other vehicles that routinely tow heavy loads. The slots draw in extra air between the rotors and the brake pads. This gives the rotors better cooling and heat dissipation. Like drilled rotors, they wear down faster and won’t last as long. 

Drilled and slotted – these rotors combine the best of both drilled and slotted rotors. They use both drilled holes and slots set in a spiral pattern to help with better heat dissipation and debris removal. You’ll find these on high-performance vehicles that require top-tier cooling and heat removal to achieve their performance. They are also at the top of the expense list. 

What are the signs of bad rotors?

When brake rotors wear down, they produce a number of signs to warn you of a potential problem. Acting fast may reduce the repair work, and will also prevent further damage to the braking system. 

A vibration in the steering wheel

This can’t be missed. As you press down on the brake pedal, a noticeable vibration occurs in the steering wheel. As you step on the brake, the brake pads press against the rotors, and the rotors gain heat quickly. This heat can cause the rotors to wear down unevenly, creating unevenness across the surface area. As the brake pad hits these wear marks, it causes the vibration to move up the braking system and into the steering wheel. 

A screeching sound

You can’t miss a screeching sound. It’s caused when the brake pads engage with a rotor that has developed grooves over time. As the surface area of the pads connects with the rotor, it creates a high-pitched sound that’s hard to ignore. You won’t have to ask twice if your brakes need a little TLC. A mechanic can pinpoint the problem, whether it stems from the brake pads, brake rotors, or somewhere else in the system. 

A blue color on the rotor surface

Excessive heat can quite literally change the color of the rotors. To check for blue spots on the rotor, kneel down and look beyond the wheels and wheel spokes. The rotor disc sets behind. If you notice a blue color anywhere on the surface, it’s worth a trip to the mechanics. If heat is compromising the brake rotor in any way, the damage could extend throughout the braking system. That puts you at risk every time you drive. 

Excessive wear

When a manufacturer designs every part on a vehicle, they set guidelines in place as to how it will perform under normal wear. That changes situation to situation. Your car may stay within the guidelines, or may move beyond depending on what you face each day. That’s why it’s a good idea to perform visual checks from time to time, as well as schedule regular maintenance visits to ensure everything is working well. 

How to avoid rotor breakdown

While rotors are designed for a lifetime of use, not all rotors last the life of a car. Especially with today’s technology where cars can move 250,000 miles or more over the life of the car. 

Just like brake pads, brake rotors are impacted just a little bit every time you take your vehicle out for a drive. The more miles you put on the vehicle, the greater chance of it wearing out over time. 

The exact lifespan depends on:

  • The quality of the rotor
  • How efficiently the rotor dissipates heat
  • The type of brake pad used
  • How you drive
  • Where you drive
  • Climate
  • Exposure to elements like rock salt and mag-chloride
  • How aggressively you brake

A Guide To Brake Calipers

by

Car maintenance for most people can be divided into two categories: the parts you understand, and the parts you don’t.

As a driver, changing the motor oil, replacing tires, and fixing the brakes when they squeak is pretty commonplace. We understand the process, know the warning signs, and fit those duties into our routines. 

But what about digging deeper? What about maintaining your car’s brake calipers. 

What are brake calipers?

Glad you asked. 

What is a brake caliper?

The brake caliper is the part of a vehicle that pushes the brake pad to the brake rotor to effectively bring your car to a halt. It’s hydraulic, which uses fluid pressure to cause movement. 

Brake calipers resemble a clamp, and partially frame the brake rotor. The caliper houses the car’s brake pads and pistons, creating friction as it slows the vehicle down. They are the heart of the braking system in vehicles that use disc brakes. 

Overall, brake calipers have two functions:

1. They guide the brake pads. Brake calipers aren’t an on/off component. Instead, they’re used to guide your vehicle along based on traffic conditions. A little pressure slows you down. More pressure brings you to a stop. Brake calipers have a design feature that ensures the brake pads are always efficient and reliable for the overall braking process. 

2. They convert brake fluid into mechanical movement. This process uses hydraulic brake fluid for the braking action within your vehicle. Without the brake caliper, this process wouldn’t take place as effectively as it does, keeping you safe in the process.  

A Guide To Brake Calipers

How do brake calipers operate?

To understand how a brake caliper operates, you need to step back and look at the entire braking system. 

When you apply the brakes, a piston is pushed into motion, putting pressure on the brake fluid in the master cylinder. The brake fluid moves through hoses in the brake lines, from the master cylinder to the brake caliper. 

This fluid pressure creates movement in the caliper pistons, resulting in the brake pads pushing forward to make contact with the rotor. Different vehicles use different types of calipers, which each have varying amounts of pistons. This squeezing action causes friction against the moving rotor, causing it to slow. More pressure means more slowing action, reducing the speed or bringing it to a halt altogether. 

When you release pressure on the brake pedal, the situation reverses. Hydraulic fluid returns to the master cylinder, and the brake caliper pistons return to their resting position. It sits in waiting for the action to arise again. 

As you step on the brake pedal, fluid pressure is released to all four wheels simultaneously, in the same quantity. This results in balanced braking, and ensures your vehicle’s safety. 

What are the two types of brake calipers?

Brake calipers come in two categories: floating and fixed. They differ in design, mourning, and operation. 

Floating calipers are compact and lightweight. They lack power when compared to a fixed caliper. Instead of being mounted rigidly to the rotor, they slide freely on lubricated pins and bushings. Hydraulics moves the piston and squeezes the inboard brake pads against the brake disc when you step on the brake pedal. That gives the caliper free movement to move along the rotor on the backside, creating clamping action as necessary for control and movement. 

Fixed calipers have multiple pistons that make them more powerful than floating. They are more suitable when a lot of power is needed – racing cars or heavy vehicles that require a lot of stopping power. They have more braking force distribution, and produce a firmer, more powerful grip of the rotor as you press down on the pedal. 

Both have advantages and disadvantages. Floating calipers are the most commonly used by manufacturers today. Check with your owner’s manual to determine which is used in your vehicle. 

The signs your calipers need replacing

Whale brake pads will need replacing over the lifetime of a vehicle, brake calipers are designed to last the life of the car. That isn’t always the case. If they are damaged in any way, you’ll start to notice the way your car drives. 

Vehicle pulls to one side when driving or braking

If your car seems to pull to one side while driving, the caliper may be the problem. The pistons move in and out from the hydraulic pressure from the master cylinder. If there is debris or corrosion, it can cause these pistons to freeze up. This will result in the brake pad being unable to connect properly with the rotor. The car will pull towards the side of the damaged caliper when the pistons fail, or away from the damaged side if the brake pad fails to connect with the rotor. This can happen while driving or during braking. 

Squealing or rubbing noises

When parts don’t operate the way they should, they can create noise from the areas impacted. While brake pad damage makes a distinct noise every time you apply the brakes, calipers will produce noise whether the brakes are applied or not. When you notice a high-pitched squealing or a metallic rubbing noise while driving and it doesn’t go away, bring your vehicle in as soon as possible, as this can lead to complete brake failure. 

Uneven brake pad damage

Brake pads are designed to last 30,000 to 70,000 miles. Because brakes are precise in function, both sides of the car should wear down at approximately the same time. If one brake pad is distinctly different than the other when you replace them, it could be a sign there is something wrong with the brake caliper. 

Brake fluid leak

Anytime you notice brake fluid leaks around the car, it’s a sign of damage. Brake fluid is a light yellow color that may darken as it ages. If you touch it, it has an oily, slippery feel. If a caliper leaks, it may cause a slight oily spot on the ground inside the tire. Different things could cause this, so it’s important to inspect them as soon as possible. 

What happens if you don’t break in car brakes?

by

Getting new brakes on your vehicle? Be sure to break them in the right way as you drive shortly after installation. It’s the only way to ensure performance over the life of the brakes. 

Breaking in new brakes is also known as bedding-in the brake pads and rotors. If you don’t properly bed in brakes, you may experience problems with the braking system down the road, such as warped discs, uneven brake pad wear, or noise brakes every time you tap on the brake pedal. 

Every time you install new brakes, the bedding-in process should be performed slowly for maximum effect. Most brake pads take 300 to 400 miles to fully break in and remove the transfer film from the rotors. 

For most drivers, this simply means driving at your normal pace. But being aware of the process from the moment you drive out of the service station will ensure maximum results. 

What is bedding-in? 

If you’re getting new brake pads and rotors, take a look at the surface area of the old equipment. You’ll notice that old rotors have a shiny grayish-blue glaze on the surface. This is known as pad transfer. It comes from brake pads pushing up against the rotor many times over the life of the equipment. Brake pads create high friction to slow down and stop a vehicle. The material from the brake pad deposits onto the rotor over time, creating friction and helping your vehicle come to a stop. Pad transfer lays the foundation for a good braking system. 

What happens if you don’t break in car brakes?

When you install new brake pads and rotors, this process hasn’t occurred. Brake pads and rotors are still two separate pieces of equipment. They need time to come together and function well. 

Why you should break in car brakes 

As you drive away from the service station for the first time after having new brake pads and rotors installed, the two start working together every time you slow down or come to a stop. The brake pad connects with the rotor, and starts leaving traces of pad transfer on the surface. 

If you pounce on the brakes and perform this process too quickly, the pad can transfer quickly onto the rotor. This can cause an uneven surface area of pad transfer on the rotor. As you drive and this process continues to build, new pad material will build on this surface, creating an uneven texture on the rotor. In most cases, this will eventually be diagnosed as a “warped rotor”. The entire thing can be avoided by spending a little extra time after installation driving carefully to allow this process to occur. 

Breaking in your brakes: the bed-in process

While many drivers bed-in new brakes through everyday driving, it’s important to understand the process if you wish to ensure proper breaking in of your car’s brakes. It requires Quickly heating and cooling the brakes in repeated movements to ensure proper pad transfer. It looks like this:

Find a safe place to drive – you’ll need space to reach up to 45 to 50 mph, and be able to quickly stop without impacting drivers around you. Ensure your safety and those around you first. 

Warm-up – start with four normal stops. Bring your vehicle up to 30 mph or so, and bring your vehicle to a controlled stop. 

Bed-in – perform eight more aggressive stops where you bring the vehicle up to around 45 mph, and bring it to a controlled stop. Be firm and aggressive with the braking, ensuring the wheels don’t lock up.

Cool-down – park your vehicle and allow it to completely cool down for at least an hour. 

Then drive your vehicle as you normally would. Your braking system is ready to go. 

Other maintenance items to do when installing new brakes

Now that you know how to break in new brakes, you should also know that to keep your braking system in good condition, there are a few other things a technician will do as they install new brakes. 

Check the brake fluid

Brake fluid is a chemical solution used to keep the hydraulic brakes working correctly in all modern vehicles. It is designed to boost your foot’s power every time you step on the brake pedal, increasing the pressure of your car’s brakes. Without brake fluid, you would need a lot more force to slow your vehicle and bring it to a stop. 

When you work on the brake system, it’s always a good idea to check the brake fluid and ensure it’s clear. When brake fluid is in good condition, it’s a lighter, clearer color with a thicker viscosity. The darker and thinner it becomes, the more compromised it may be. It will be replaced if necessary. 

Brake system check

Ensure the entire braking system is working well. From the brake pedal to brake fluid, calipers, and brake pads, each piece of the braking system is important to ensure safety while driving. Things like caliper guide pins can become rusty over time. They can also tighten, needing lubricant to ensure proper movement once again. A reputable mechanic will ensure every piece in the braking system is operational and working well before driving away. 

Slotted or drilled rotors

Improvements are made continually in the world of automotive. With technological advances come better ways to maintain your vehicle. Are you running with the best brake pads and rotors for your car and the way you drive? 

Rotors come in slotted and drilled format. While slotted rotors don’t improve heat transfer, they can enhance brake output by removing dust and debris that can sometimes become stuck between the pads and rotors. This dust reduces friction force, which prevents the pads and rotors from flush contact. Drilled will give better with normal city driving, while slotted may be better with high performance vehicles.

Your brakes are one of the most important safety systems in your vehicle. Without brakes, you wouldn’t be able to slow down and stop, and keep your car under control. 

For a well maintained vehicle, be sure your brakes are in good working condition. And when you get new brakes, break new brakes in properly for a full, long life. 

How can we help you keep your car well maintained? 

Was The Winter Hard On Your Brakes? Cold Weather Brake Problems

by

Cold weather and Colorado go hand in hand. 

While we love skiing, the occasional blizzard, and days off from work and school, sometimes the cold weather can be a bit challenging. Heading out to a car that won’t start can be a bit frustrating. Finding out your brakes aren’t working can be dangerous at best. 

Brakes are one of the most critical systems of today’s modern cars. Have you ever noticed changes in how your car brakes on the coldest days of the year? You’re not alone. We are often flooded with calls when the temperatures dip to zero and below. 

Cold weather brake problems are different from issues you may experience at other times of the year. While cold weather doesn’t directly impact your brake system the same as a car battery, it can change how your car handles and moves. Being aware of the impact cold weather has on brakes will keep you safe no matter what the thermometer reads when you head out into the world. 

Cold weather may impact the brake lines

What keeps your brakes in good working condition is the brake fluid. The freezing point of brake fluid is -40 degrees Fahrenheit, but the freezing point isn’t an all-or-nothing process. Instead, brake fluid starts to congeal the colder it gets. And as the brake fluid thickens, you’ll notice it in the way your car handles. 

Was The Winter Hard On Your Brakes? Cold Weather Brake Problems

You might be thinking that the Front Range never sees -40 degrees Fahrenheit temperatures. Yet we do see the temperatures creep well below zero almost every winter season. 

If your brake fluid is fresh and in top shape, it will continue to work fine as the temperatures drop. But if you don’t keep your brakes well maintained, that could be a problem. 

Over time, brake fluid absorbs moisture from the air. Even though the braking system is mostly airtight, the brake fluid will still come in contact with air and moisture. And when there is moisture in the brake lines, even 32 degrees Fahrenheit can be a problem. 

Studies show that up to one in five cars is driving around with water in the brake line. If you haven’t had your vehicle inspected, or asked about having your brake lines flushed in a while, it could present a problem on the next bitter cold day. 

Cold weather could actually cause too much heat

Sounds counterintuitive, doesn’t it? How could cold weather cause too much heat? 

When ice, snow, and all that comes with winter driving impacts your brake pads, you’ll start applying more pressure to the brake pedal every time you slow down or come to a stop. More pressure means more action in the braking system. And that can cause it to get very hot. Too much heat and it causes the entire braking system to overheat. 

While your brake system is designed to withstand intense amounts of heat, everything has a breaking point. As the brake pads wear down, the responsiveness wanes, and you might start hearing funny squealing sounds. 

Regular inspections will ensure that every point in your braking system is operating at maximum capacity. You can also change your driving patterns so you’re not riding the brakes. Give yourself plenty of room between you and the car in front of you, so you’re not tapping or slamming on the brakes. 

Cold weather can impact the undercarriage

Colorado driving is a consistent challenge of navigating whatever Mother Nature has to dish out. When ice or snow is in the forecast, the city moves into action, adding things like mag-chloride to the streets, and sanding and adding de-icer to slippery spots to help keep you safe. 

All of that takes its toll on your undercarriage. 

It builds up in every nook and cranny it can find. All of those chemicals can accelerate rust and corrosion, damaging individual parts and components. 

The most obvious signs come in the form of rust. You may see evidence if you perform a visual check. If you don’t clean the chemicals away shortly after they are applied, they can continue to build (and continue to damage) on every part underneath your vehicle. It can impact your braking ability, the way your emergency brake works, cause parts to rattle and fall off, and decrease the functionality of your vehicle. 

On those 70 degree days that fall in between storms, it’s a good idea to head to your local car wash and give the undercarriage a good cleaning. Regular inspections are also a good way for allowing a mechanic to take a look underneath and ensure every part is still in good working condition. 

Has winter weather impacted your brake system?

March is the snowiest month in Colorado. Here along the Front Range, snow is possible almost every month of the year. And when you take a ride into the mountains, road conditions can change quite rapidly. 

One of the most important systems on your vehicle is the brakes. If it’s been a while since you’ve had them checked, now may be the time. 

A harsh winter can lead to car problems you might not notice until they show up in a big way. Preventative maintenance is the easiest way to ensure you and your passengers stay safe. 

The next time you’re out driving, pay attention to what your car is trying to tell you. Does it squeal, squeak, or bang? Do you sense your brakes take a little longer to engage? Do you notice a funny smell, or see potential problems as you walk around your car? Warning signs are there for a reason. They’re designed to give you a chance to bring your car in before bigger problems arise. 

Whether you head to the hills for ski weekends, or simply drive to work every day, the Colorado winters can do a lot of damage to your vehicle.

Make today the day you fight back against everything this winter dished out. Cold weather can impact your brake system in harmful ways. An inspection will ensure it’s still driving well. 

How Long Can You Drive With Worn Brake Pads?

by

Brake pads are one of the most critical pieces of equipment built into your car. If your brake pads aren’t working, you won’t be able to slow the car to a stop, or keep it under control as you drive. 

Worn brake pads won’t handle the way new brake pads do. That’s why manufacturers build in warning signals to alert you to the fact that your brake pads are failing. There’s no mistaking the high pitched squeal brake pads make at the end-of-life when you press down on the brake pedal and the metal of the brake pad connects with the metal of the brake rotor. 

You’ll notice it. And so will everyone else around you. 

Brake pads last somewhere between 30,000 and 70,000 miles. Check with your owner’s manual for specifics. 

But even with those general guidelines in place, brake pad life changes based on your driving patterns. There are many things you do that will ultimately determine how long your brake pads will last. 

What effects brake pad wear

Driving habits

Your daily commute is the biggest indicator of how well your brake pads will handle over time. Are you an aggressive driver? Do you ride the brakes? Do you pounce on the brake pedal reacting to the drivers around you? Is your terrain flat, or do you drive over a variety of steep grades? Do you coast to a stop, or slam on the brakes? Brake pads will wear differently depending on your approach. Brake pads are all about safety – abrupt stops are sometimes necessary. But smoothing out your normal driving patterns will ensure a long life for your brake pads. 

How Long Can You Drive With Worn Brake Pads?

Vehicle weight

Cars are different from trucks. A heavier vehicle will require more braking action to come to a complete stop. It also depends on how loaded your vehicle is. Many drivers across Colorado keep items from their active lifestyle inside their vehicles at all times. Bike racks. Cargo toppers. Sports equipment in the back. All of that requires more action to bring the car to a stop. Your brakes will also have more stress if you regularly pull campers or trailers, especially going up and down the mountain. The more stress your brake pads endure, the shorter lifespan they will have. 

Driving environment

We have a variety of driving conditions here along the Front Range. Is your driving primarily urban, or do you regularly take dirt roads? Do you live in the city, or high up in the mountains? Steep elevations impact driving differently than living out on the plains. Your brakes will also endure changing weather conditions, sometimes all in the same day. Temperatures rising into the three digits. Ice and snow making hazardous driving conditions. All of that impacts how often you rely on your brakes for slowing and stopping. 

Brake materials

Not all brake pads are alike. Brake pads are created from several different compounds to match different driving needs. Harder materials work better when performance is required. Softer materials work better at lower speeds, such as when you primarily drive in city conditions. Steel or metal brake pads are the most common materials, and work well in average driving conditions. Carbon-ceramic brakes last longer than their metal counterparts, but are more expensive and are primarily for better performance. Your vehicle’s manufacturer has recommendations for which brake pads are best for your driving conditions. Or talk with one of our technicians for more information. 

What happens if you keep driving on worn brake pads? 

Have you reached a point where you know you’ll have to replace your brake pads soon, but you’re trying to get the most life out of them? Several things can happen if you keep driving on worn brake pads. 

Your car will need more space to slow and stop

Worn down brake pads won’t be as functional as new brake pads. That means your vehicle will require more surface area to slow and come to a stop. Response time can change rapidly as your brake pads wear, especially if they wear unevenly. If it feels like it takes more force from you stepping on the brake pedal, it’s a good indicator there are problems with your brake pads. 

Your car vibrates as you brake

When brake pads work well, you’ll come to a smooth stop. As they wear down, it adds pressure to their ability to slow and stop. Especially if they wear unevenly, you’ll start to notice this in the stopping action. You’ll be able to feel the vibrations throughout the car. 

Other parts can be impacted

It’s not just your brake pads that are at risk. The more worn they become, the more at-risk other parts on your vehicle are too. Brake pads are part of an intricate system where if one component is damaged, it can impact many others too. If brake pads wear past the wear mark, they can damage the brake rotors. The metal of the brake pad grinds into the rotors every time you push down on the brake pedal. The heat from this pressure squeezes against the rotor and can warp or crack it over time. If your car needs greater force to come to a stop, this will also impact your tires. Constant slamming on the brakes causes your tires to wear unevenly, wearing down before their estimated lifespan. All of this can add up to more component replacement, making your repair costs rise.  

How long can you drive on worn brake pads?  

Brake pads are designed to last anywhere from 30,000 to 70,000 miles. How many your car gets will be determined by your day to day driving conditions. 

But once you detect your brake pads are no longer working as designed, what happens to the rest of your vehicle largely depends on your actions. 

Can you drive on worn brake pads? Sure. For a while. But it will quickly materialize into many other problems, require more repair work, and potentially put you and those around you at risk. 

Is it time for new brake pads for your vehicle? 

What Happens If You Drive With a Bad Brake Caliper?

by

When you hop into your car and drive to school or work, you don’t think much about how it operates. You turn the key and go. 

Yet if you stop to think about each system, chances are you’d push the braking system to the top of the list in importance. After all, without the braking system, your car would experience extensive damage pretty quickly, while you may face injury yourself. 

How much do you know about the braking system? Brake pads. Rotors. Brake fluid. Calipers. There are several major components that create an effective braking system. If any one piece is damaged or not working correctly, 

Understanding brake calipers

While most people understand that pushing on the brake pedals initiates the braking process, they don’t understand a brake caliper’s job. Brake calipers are a crucial part of making your car slow down and come to a stop as you push down on the brake pedal. 

A caliper is a component of the disc brake system, which is what most cars have in the front brakes. 

What Happens If You Drive With a Bad Brake Caliper?

The brake caliper sits like a clamp on a wheel’s rotor. You can actually see it on most cars if you glance through the spokes on your wheel. The caliper houses the brake pads and pistons. Its main purpose is to clamp down on the rotor, creating friction with the brake rotors. 

When you press down on the brake pedal, brake fluid creates pressure, causing the piston to move against the brake pad, which in turn pushes it against the brake rotor. The more pressure you put on the brake pedal, the more friction between the pads and rotors. Until your vehicle comes to a complete stop. 

The brake caliper sits inside the wheel, and is connected to the master cylinder through a series of tubes, hoses and valves. These connections push brake fluid through the system to make it work. If any piece or component in this system isn’t operating well, it can greatly impact the braking process. And that can put you and the people around you in danger. 

What happens if you drive on a bad brake caliper?

If you drive with a bad brake caliper, you’re risking the entire braking system not operating as it should. 

The caliper houses the brake pads and pistons. A stuck caliper means the brake pad will not completely pull away from the brake rotor. A part of the brake pad will have constant pressure against the rotor while you drive. Which also means part of the braking system will be engaged all the time. 

This can add stress to the entire braking system. It can also add stress to the transmission, which can cause failure earlier. 

At a minimum, it will cause your brake pad to wear down prematurely. This means you’ll be replacing your brake pads more frequently, and putting yourself at risk if it doesn’t engage properly when you step on the brake pedal. 

As soon as you notice a problem, fixing it is your best solution. 

When is it time to replace brake calipers?

While you might not notice a problem right away, eventually you’ll start to notice your brakes aren’t working the way they should. A bad caliper can cause a variety of warning signs, signaling to you a potential problem. 

Pulling to the right or left – one of the biggest warning signs is a vehicle that doesn’t drive straight. As you’re driving down the road, does your vehicle pull to the right or left? As you’re braking, do you notice the pull get more prominent? If one of the calipers is bad, it’ll impact the connection between the brake pad and the rotor, causing your vehicle’s stopping function to be compromised. 

Heat coming off the wheel – as you can imagine, when the brake pad connects with the rotor, it creates a lot of friction. This friction gives off tremendous heat. Under normal driving conditions, this heat dissipates quickly. But if the connection is constant, the heat continues to grow. If you suspect a stuck caliper, stop the vehicle and turn off the engine. Place your hand near the wheel without touching it. Can you feel more heat than the other wheels? This may be a sign of a stuck caliper. Bring it in for an inspection right away. 

Dirty brake pads – imagine all the wear and tear your brake pads see as you drive. From ice and snow, to the one-hundred degree days in the summer months, your brake pads deal with a lot of dirt and debris kicked up from the road as you drive. Sometimes that dirt can build up on your brake pads, causing the caliper to stick. A mechanic may be able to clean them and get them working once again. If they are worn, you can replace the brake pads before they cause any more problems. 

Brake hose problems – the braking system contains multiple parts to remain in good working condition. If the brake hose wears out, it won’t deliver brake fluid properly to the various parts. Without brake fluid, the master cylinder won’t be able to control the brake caliper movement. This can be assessed by a mechanic, and a brake hose replacement may be necessary. 

The best way to keep your calipers in good working condition is to ensure your brake pads are replaced and the brake fluid is topped off. Brake pads are the most frequently part replaced on the braking system, with most brake pads being replaced every 10,000 to 20,000 miles. 

Tracking your maintenance items can alert you to potential problems before they exist. Are your brake pads nearing your vehicle’s suggested guidelines? Are you pushing the 20,000 mile marker? It may be time to schedule an inspection with one of our mechanics. We can evaluate the entire system, and ensure your brakes are safe and ready to work every time you drive. 

This Is How You Tell If Your Brake Calipers Need Replacement or Repair

by

The braking system is one of the most important systems on your vehicle. While you might be familiar with brake pads and brake fluid, brake calipers are a little more obscure. What are they? What do they do? And how do you maintain them throughout the life of your car? 

What are brake calipers?

Owning a car means performing regular maintenance. For your braking system, the most often parts to be replaced include the brake pads. 

Manufacturers recommend replacing brake pads every 10,000 to 20,000 miles. When it comes to the brake rotors, you have a bit longer. Rotors should be replaced every 60,000 to 70,000 miles to ensure your braking system remains in great shape. While not as common as motor oil, your brake fluid should still be replaced every four to five years. If you haven’t read through your owner’s manual, it’s a good thing to keep on hand. 

Brake calipers also need replacing over time. Through wear and tear, they lose their ability to clamp down and relax the brake pads as you apply and release pressure. 

A brake caliper is a part of the disc brake system, which is what most vehicles have on their front brakes. You can see it sitting on your wheel if you look through the spokes. The brake caliper houses the brake pads and pistons. Its sole job is to slow the car’s wheels as you press down on the brake pedal, to create friction against the brake rotors. 

Inside the caliper, a powerful piston uses pressure from hydraulic fluid to press the brake pads against the brake rotor. When working properly, the calipers move effortlessly based on the amount of pressure from the brake pedal. 

This Is How You Tell If Your Brake Calipers Need Replacement or Repair

When something in the system breaks, wears down, or stops altogether, that’s when you have a problem. 

Brake caliper alerts – how to know when you have a problem

Like other systems on your vehicle, the braking system has all kinds of warning signals to alert you when things aren’t working correctly. 

Most vehicles have sensors to art you to braking problems. The brake light on your dashboard will illuminate when the sensors detect something is wrong within the system. 

The brake light could trigger if you’re low on brake fluid, or the pressure isn’t within set guidelines. It can also alert you to brake pads wearing down if the car is equipped with pad sensors. The dashboard light is designed to give you plenty of time to set up a service visit and fix the problem before it escalates. 

Unfortunately, problems with the brake calipers can be a little more challenging to detect. 

Where’s the brake caliper problem?

There are several ways you can identify and prevent further brake caliper breakdown. 

Noises, smells, and feelings

Driving is often one of those mindless tasks you perform on autopilot. But it is a good idea to stay alert and pay attention to what your car is trying to tell you. The first problem with any system is often identified through one of your senses. 

Does your car drive differently? A malfunctioning caliper can cause your vehicle to pull to one side as you drive. This is due to an unbalanced braking system. Because one caliper doesn’t provide pressure in the same manner as the other side, you’ll notice your car lurching forward, or pulling to one side as you slow and stop. 

You may also hear a squealing or grinding sound. This happens when brake pads run thin, and can’t connect with the rotors efficiently. Is it the brake pad, or is it a caliper malfunctioning that caused it to wear down before its time? If you’re nearing the lifespan of your brake pads, it may be the problem. But if you still have life left on them, it may be worth further investigation. 

Too much pressure on the braking system can also ramp up the heat within the system. If you notice a burning chemical smell near one of the front wheels, it may be a sign of overheating from the brake pads and the bonding agent. 

Do a visual inspection

If you’ve ever boarded a plane early, and watched outside the window, chances are you’ve seen the pilot walk around doing a visual inspection. Why? He’s in charge of the plane, keeping the passengers safe, and the plane in good working condition. It’s up to him to decide if it’s okay to fly, and if he’s comfortable with the mechanics and technology he’s been given. 

Driving works similarly, though most of us rarely take a walk around our vehicles before jumping in behind the wheel each time we drive. But there is something to learn from a pilot – it’s a good idea to do a visual check from time to time. Do you notice tire tread wearing unevenly? Is there liquid accumulating near the caliper or the wheel? Keep an eye on anything that looks suspicious, and bring it in for inspection at your earliest convenience. 

Proper maintenance means prevention

Luckily, it won’t take much time out of your day to ensure your vehicle is working well. With an occasional visual inspection, and a moment or two paying attention to what your car is trying to tell you, you’ll be able to drive securely with the knowledge that everything is working well. 

Bring in your car for regular motor oil changes. Ensure your tires are properly inflated, and your wheels are properly balanced. 

Let a mechanic run through a checklist to ensure everything is working well. You can schedule this at the start of each season. Or if you’re heading out on the open road. It’s a great way to keep your security in check to ensure something bigger doesn’t happen. 

Braking problems? It might be caliper issues

Your brake calipers are designed to last 100,000 miles or more. They aren’t a component that needs to be replaced often. 

Being aware of potential signs of a problem will ensure your braking system continues to work well. It’s the best way to keep your passengers safe, and your vehicle operating well. 

When was the last time you had your braking system inspected?  

Simple Ways To Determine If Your Brakes Have Problems

by

Driving a car is an automatic function of our lives. Within weeks of purchasing it, we adjust to its sounds, noises, and movements. We expect it to work … until it doesn’t. 

The more aware you are of the sounds, noises, and movements, the greater chance you have of noticing when problems occur. Solving the issue before it escalates can save you time, energy, and money. It may also save your life. 

Your brake system is one of the most vital systems on your car. If your brakes fail, it can put you in a precarious situation. Luckily, your brake system has warning signs that potential problems are occurring. If you notice these early, you can fix the problem before it escalates. What should you watch for?

Watch for the brake light on your dashboard

We see it quite frequently where a driver brings their vehicle in with several dashboard icons lit. These sensors go off for a reason; don’t ignore them. They are providing you with ample warning that your vehicle no longer meets manufacturer’s guidelines. 

If the brake light indicator appears on the dashboard, it’s providing you with a warning that it’s either time for a routine maintenance check, or there’s a problem within the system. An illuminated brake light could signify that your vehicle has low levels of brake fluid. If this is left unchecked for too long, it could lead to serious braking issues. Low fluid impacts stopping distance, and could impact how the brake pads wear. 

Simple Ways To Determine If Your Brakes Have Problems

Schedule your appointment soon to avoid bigger problems. 

Listen for squealing or squeaking noises

Cars make a lot of noise throughout your drive. You can easily pick up on noises as they change over time if you stay fully aware. New noises coming from your brakes aren’t always a bad thing, but they might be indicators of a potential problem. 

How long do they last? Do you hear the noise over and over again? Sometimes a rock or debris can impact sound. But as it leaves the system, your car should return to normal.  

Brake pads are built with wear indicators that produce a squealing noise. This high-pitched sound will continue to build the more you drive. This ensures you can’t ignore it. You’ll notice it every time you step on the brakes. 

Watch for problems with anti-lock brakes

Most modern day cars come with anti-lock braking systems that offer a key safety component to help your drive. ABS is designed to help prevent your brakes from locking up during emergency situations. It also helps your tires from losing traction on icy or slippery roads when you step on the brakes. 

In most cases, if your anti-lock brakes have a problem, you’ll see an icon on your dashboard illuminate. Problems can range from a damaged ABS tone ring to a faulty speed sensor. The best way to determine where the problem lies is to bring it in for a diagnostic test to see what’s triggering the warning light. 

Notice brakes get spongy to the touch

When you first get your vehicle, your brakes respond immediately to your touch. As brakes wear down, it takes more pressure to achieve the same results. As you press down on the brake pedal, it moves closer to the floor, and it takes on a somewhat spongy feel. Causes can include:

  • Air in the brake line. This is often caused by a brake fluid leak or if the brake fluid is low. 
  • Damage to the brake line. If you’ve been in a car crash, or your car was damaged in any way, it could have impacted the brake line. Age can also impact it, allowing the line to become brittle, cracked, or rusted out 
  • Low brake fluid. If there is a leak in the system, brake fluid might not be at the recommended level. 
  • Master cylinder issues. The master cylinder controls brake fluid levels. If it isn’t working correctly, it isn’t sending brake fluid in the quantity needed. It will be more difficult to brake as you’re driving. 

You notice a shake or vibration when steering

If the steering wheel shakes or vibrates when you apply the brakes, it could be a sign of a bigger problem. Common problems include:

  • Worn brake pads. Any time the brake pads reach end of life, it can impact the way your car drives. When the pads can no longer grip the rotors as intended, it can cause the steering wheel to shake. 
  • Warped rotors. When applying the brakes, the brake pads connect with the rotors to stop the wheels from spinning. Over time, the rotor can wear down. If it does so unevenly, it can impact the brake friction when you apply the brakes. This is why it’s important to fix the brake pads quickly, as they are less expensive and easier to repair than the rotor.  

You notice a burning smell

If the brakes get too hot, they can leave off a sharp, chemical odor. If you notice this coming back from a day of skiing, for example, it’s best to pull over and let your brakes cool before driving again. Double check the parking brake to ensure it’s not engaged. If there’s smoke coming from the wheel, it may be a caliper that is malfunctioning. If you aren’t sure, your safest bet is to have your car towed. It keeps you safe and ensures further damage isn’t caused to your brake system. 

Your car pulls to the left or right 

While this can be caused by a variety of problems, it might be from a problem with your brake system. If it’s caused by the front brakes, one brake may be working while the other is not. That will cause your car to handle differently as you apply the brake, with your car moving right or left depending on which brake isn’t working. Any time you notice your car not driving in a straight line, it’s time to have an inspection to ensure it’s working correctly. 

Don’t ignore problems with your brakes

Even the smallest issues can cause your brakes to fail. Any warning sign is designed to give you a chance to bring your car in for inspection before you have more serious problems.

How To Check and Inspect Your Brake Pads to Avoid Brake Failure

by

The braking system on your car is probably something you don’t think much about. You get in. You drive. And when you press down on the brake pedal, you slow down and eventually come to a stop. 

What if they didn’t work? 

Like everything on your vehicle, brakes have a limited lifespan. The various components wear down a little each time you use them, and eventually become so worn they need repair or replacement. 

How big a risk is brake failure?

Why brakes fail

When you press down on your brake pedal, that pressure is transferred into the brake lines. Brake fluid transmits that pressure to the brakes themselves, which ultimately causes you to slow down and come to a stop. 

There are two different kinds of brakes on vehicles today: drum and disc. In both, the pressure from the brake lines pushes the drum or disk against the wheel itself to slow it down. 

Brakes can fail from a variety of events, but in general, can be lumped into two categories. 

A leaky brake line – this is when a leak forms somewhere in the brake line. Brake fluid slowly drains from the system until there isn’t enough left to move pressure from the brake pedal to the tires. 

Worn out disc or drum – this is when one or more parts to the brake system itself wear out. If brake pads, shoes, rotors, or any other part of the drum or disc brake system wear down enough to prevent proper friction on the wheels to stop them, you’re at risk. 

Brake failure – quick or slow?

The good news is that car manufacturers have built a series of safety features into every system on your vehicle, to alert you of potentially dangerous situations long before they occur. As problems arise within the braking system, you’ll be alerted by a change in the way your brakes handle, a noise when you press on the brake pedal, or even a change in the way your car handles. If you step on the brake pedal and it feels spongy or pulls to one side, it’s a sign you have a problem with the brakes. Schedule an appointment with one of our mechanics as soon as possible to avoid further damage and increased risk. 

How To Check and Inspect Your Brake Pads to Avoid Brake Failure

Brake pads – the most common problem

While multiple things can potentially go wrong within your braking system, in most cases, you’ll replace the brake pads more frequently than any other part of the system. 

Brake pads will last around 40,000 miles on average, while brake rotors can last as much as three times as long. Why? Brake pads are responsible for bringing your car to a stop. When you press down on the brake pedal, it’s the brake pad that presses up against the rotor, slowing down the wheel in the process. Eventually, this material will wear down, leaving only the metal baking in place. 

While 40,000 is a rough estimate, many things can alter how many miles you’ll receive on each set of brake pads you install. 

  • Do you drive mostly on the highway or in town?
  • Do you frequently ride the brakes?
  • Are you an aggressive driver, often pouncing on the brake pedal?
  • Who manufactured your brake pads?

Brake pads are made of frictional material bonded to a metal backing plate. Brake pads are typically made from one of three different materials:

Organic – most vehicles on the road today use organic brake pads. They are also known as NAO pads, or non-asbestos organic pads. These pads are made of materials such as carbon, fiber, glass, rubber, and sometimes Kevlar mixed with resins to help bond it all together. While organic pads are usually the least expensive, they also wear down faster than the other types of pads. Still, they are a good choice for average daily driving conditions. 

Semi-metallic –  when you purchased your vehicle, if it didn’t come with organic brake pads, there’s a good chance semi-metallic brake pads were installed instead. These are often a popular choice on trucks or larger SUVs. Semi-metallic brake pads are created from metal shavings such as copper, steel, brass, and possibly graphite. They are bound together by resin. They are best suited for more rigorous driving conditions and heavy-duty use. 

Ceramic – want a brake pad somewhere in between, that offers performance as well as a comfortable ride? Ceramic brake pads may be the way to go. Ceramic brake pads are made from hard, ceramic fibers. That gives them the longest lifespan of the three types, and also the quietest ride. They handle heat very well, but instead of absorbing heat like the other brake pads, it sends it out and impacts other parts of the braking system. These are high-performance parts that can enhance your drive. 

Do a brake check and stay safe

While you drive, you should monitor the way your car handles. 

Before you get into your car, do a visual inspection occasionally to ensure your brakes are in good working condition. Do so with your car parked safely and the ignition off. 

Look at the wheels. Do you notice brake dust on the wheel? How much? If you notice it increasing over time, it’s something you should bring up on your next visit. 

On some cars, you can also see the brake pad. Notice its thickness. If it seems thin, ¼ inch or less, it may be time for replacement. Monitor this and speak with one of our mechanics on the safety of your braking system. 

When you start the car and drive, listen to your brakes. Brake pads are designed with a marker that makes noise when they need to be changed. It will get louder over time, as the material on the brake pads continues to wear. 

You should also pay attention to how your vehicle drives. You can often feel changes in the way the brake pedal moves and connects with the braking system. 

Your car is also built with a warning system. If the brake warning light comes on at any time, have it checked sooner rather than later. 

Are your brakes in good working condition?

Put Brake Replacement On Your Calendar

by

When you purchase a car, you invest in freedom. Owning a car allows you to come and go as you please. 

But owning a car takes more investment than buying an appliance for your kitchen. A toaster, mixer, or dishwasher work … until they don’t. Then you replace them and move on with your day. 

You can’t do that with a car. Your vehicle has over 10,000 parts that make it operate smoothly and efficiently. If you don’t care for these parts along the way, they can wear down, break down, and leave you stranded. 

Considering your car has thousands of parts, it’s difficult for anyone to track. Most understand that motor oil needs replacing around 3,000 miles. It’s a rule of thumb most car owners know. It’s on autopilot. 

But what about the other fluids and systems? They tend to disappear – out of sight, out of mind. 

Take your brakes, for example. Your brakes are one of the most vital systems on your vehicle. It contains dozens of parts, each of which needs maintenance throughout the years. When do your brake pads need replacing? Are the brake rotors in good shape? How about brake fluid? Get it wrong, and they might not work when you step on the brake pedal. 

What is a car maintenance schedule and why should you calendar it? 

When you own a car, maintenance becomes a part of the process. There are two ways of handling it: schedule, or as needed. When you schedule it, you catch things before they snowball. You fix minor issues before they become big problems. When you adhere to the as-needed method, your costs run higher as you only fix things when they completely break down. 

Creating a car maintenance schedule is the easiest way to stay on track. If you calendar it, you’ll take the guesswork out of when certain maintenance items should be performed. Think of it in the same manner as you do your motor oil changes, and base it on regular intervals throughout the year. 

When was the last time you sat down and flipped through your vehicle’s owner’s manual? If you’re not even sure where it is, it’s time to find it. Manufacturers create an owner’s manual to provide requirements for your vehicle’s critical components. They spell out each system, the various inspections, and replacements needed over the life of the car. Because they created the car, they are the most aware of how each system is designed to last. Using the owner’s manual, you can calendar the most important systems, knowing when you should bring your car in for inspection. 

Put Brake Replacement On Your Calendar

Some systems move to the top of your list … like the brake system

A car’s brake system is a complicated system of components that work together to give you control over your vehicle while you drive, and provide safety features to ensure you and your passengers remain safe inside. If the components work well together, your brake system will operate efficiently. If any part starts to wear down, failure can occur, causing an accident. 

Like other systems on your car, the brake system is a fairly straightforward mechanism. It starts by pressing down on the brake pedal inside your car. This releases brake fluid and moves it into a piston, which generates enough force to be able to squeeze a caliper against the car’s wheels, slowing the car down until eventually, it comes to a stop. This pressure between the pistons and the calipers causes friction, which helps control the speed of the wheels. 

Of course, a brake system is made up of more than just pistons and calipers. It’s only the start of the various components that make up the braking system. Other issues can originate with the following:

Master cylinder – this is where hydraulic fluid is pushed down into the brake lines using fluid from the brake reservoir. 

Brake rotor – also known as disk brakes, each wheel uses a rotor that spins while the vehicle is in motion. The caliper rubs against the rotor to create the necessary friction to control the wheel. 

Brake drum –  this is the alternative to disk brakes, where the drum spins while a brake shoe moves inside to cause friction when you step on the brake pedal. 

Brake pad – the brake pad is attached to the caliper, creating friction as it connects with the rotor. It can be made from different materials, one of the most commonly replaced items on the braking system. 

Brake caliper – a clamp that provides force as it pushes the brake pad against the rotor using hydraulic pressure. 

Brake shoe – the alternative to the brake pad, used in brake drum systems.

Brake pedal – this is the pedal inside your vehicle. 

Brake lines – brake lines transfer brake fluid between the master cylinder and the wheels. 

Wheel sensors – on an anti-lock braking system, wheel sensors are used to detect how fast each wheel is spinning. When these sensors determine the four wheels are spinning at different rates when you slam on the brakes, it uses speed variation to take control over brake pressure and bring your car to a safe, controlled stop. 

ABS monitor – this is a computerized mechanism for controlling your braking system. It’s what tracks and controls the wheel speed sensors. 

Calender your brake maintenance to stay safe

While your car’s manufacturer will have specific guidelines, on average, the various components of the braking system will only last so many miles. 

  • Brake pads – between 20,000 and 65,000 miles
  • Brake rotors – between 30,000 and 70,000 miles
  • Brake calipers – between 75,000 and 100,000 mile
  • Brake drums – about 200,000 miles
  • Brake shoes – about 35,000 miles
  • Brake lines – every 5 to 10 years
  • ABS wheel sensors – between 30,000 and 50,000 miles

As each of these components begins to wear down, they give you ample warning before they fail. You may notice strange noises, such as screeching or squealing. A deep grinding sound is a metal sensor feature put into brake pads to alert you to wearing down. The car may pull to one side or the other if one of the brakes is malfunctioning and in need of repair. 

Paying attention to how your car operates is the best way to alert you to potential problems. When you notice a change, bring your car in and have one of our technicians inspect it, making the necessary repairs to keep you safe.
