The 7 Common Failures Of Brake Calipers (Calipers Or Caliper)

Have you noticed your vehicle pulling to one side on its own? Do you feel the brake pedal soft or spongy? These could be signs of a bad brake caliper. Don’t worry, we have created for you a list of common brake caliper failures , also known as calipers or calipers, so you will know how to identify any problem.

While brake pads need to be replaced periodically, calipers or calipers should last the life of the vehicle, but that’s not always the case. The calipers can eventually fail and compromise the overall safety of your car. Being familiar with the symptoms of a bad brake caliper or caliper will help you fix the problem right away.

What are brake calipers, calipers or calipers?

Brake calipers are fairly straightforward components. Most modern vehicles have a four-wheel disc brake system with a caliper on each wheel, while some cars have caliper disc brakes at the front and drum brakes at the rear.

When the brake pedal is depressed to apply the brakes, brake fluid flows into the individual calipers or calipers. The pressurized fluid forces a piston inside the caliper to squeeze a pair of brake pads against the brake rotor. Forcing the pads against the disc creates the friction necessary to stop the car.

Each caliper mounts (directly or indirectly) to one of the car’s steering knuckles. A brake hose supplies pressurized fluid to the caliper.

The calipers also have bleeder screws that a mechanic can open to bleed air from the brake system. They may have one or two pistons, depending on the application.

There are two basic gripper designs: fixed and floating . Fixed calipers mount directly to the steering handlebar and do not move back and forth. Floating calipers (also known as sliding calipers), on the other hand, mount to an adapter plate, which bolts to the steering knob. A set of slider pins or bolts allow the caliper to slide back and forth when the brakes are applied and released.

Common failures of brake calipers or calipers

Do you think you may have a bad brake caliper? If your car exhibits one or more of the following symptoms, you may be correct. Without further ado, here are the common failures that brake calipers present:

1- Pull to the side

A seized brake caliper or caliper sliders can cause the vehicle to pull to one side or the other when braking. Sometimes the car will also pull while driving on the highway.

2- Liquid leaks

Brake calipers, which are activated by hydraulic fluid, can develop brake fluid leaks from the piston seal or bleeder screw.

3- Spongy or soft brake pedal

A leaky caliper can cause a spongy or soft brake pedal . Additionally, a seized piston or stuck sliders can create excessive clearance between the pad and rotor, causing abnormal pedal feel.

4- Reduction of braking capacity

Obviously, if you have a faulty caliper, resulting in a soft brake pedal, your car will show reduced braking ability.

5- Uneven wear of the brake pads

Uneven brake pad wear is usually caused by binding of the caliper pins . In some cases, a stuck caliper piston can also cause uneven wear. The reason is that in both cases the pads are partially applied, causing them to drag on the rotor.

6- Sensation of drag

Obviously, if you have a faulty caliper, resulting in a soft brake pedal, your car will show reduced braking ability.

A stuck caliper can cause the pads to be pushed against the rotor while driving. As a result, the car may exhibit a drag sensation, as the brakes on the affected wheel are applied (or partially applied) at all times.

7- Abnormal noise

Over time, a seized caliper will wear out the brake pads. And when that happens, you’ll hear the familiar sound of screeching brakes. This is a problem that comes up quite a bit, which is why we’ve included it on our list of common brake caliper failures.

How to know if a brake caliper or caliper is bad?

Other problems with your vehicle can mimic a bad brake caliper. That is why it is important to carry out a thorough diagnosis if you suspect that you may have a faulty caliper.

There are several methods to fix a faulty caliper. Depending on the problem you are experiencing, you may want to check the caliper for leaks, inspect the brake pads for abnormal wear, or check the function of the caliper piston. You may also want to perform a line block test.

To complete

Don’t play with your brakes . A seized or stuck brake caliper can cause partial or complete loss of braking ability. If your vehicle exhibits any of the above symptoms and you’ve determined that you have a bad brake caliper, get it fixed immediately.

Also, you may hear some people talk about rebuilding brake calipers. But this is the 21st century and replacement calipers are cheap and plentiful; no one checks them anymore. Just buy a caliper in good condition.
