What causes rear brakes to wear unevenly?
Hear this out loudPauseIn some cases, brake rotors can wear unevenly, causing what’s known as Disc Thickness Variation (DTV). DTV can be caused by different factors, such as sticking calipers, rust, slamming on the brakes frequently, or dirt and debris getting stuck between the pad and the rotor.
How can I tell if my rear brake is a problem?
To determine if your rear brakes are the problem, you need to test them in isolation. One way to test your rear drum brakes is to apply the parking brake slightly while driving, because the parking brake uses the drum brakes in the rear.
Why does my steering wheel pull when I brake hard?
Usually, when the problem comes from one of the front brake assemblies, you’ll feel a strong pull on the steering wheel when applying the brakes. However, when the problem comes from one of the rear brake assemblies, you may not notice a pull unless you brake hard.
Can a bad front brake cause a bad rear brake?
That way, if there is a leak in one part of the system, it should only affect one front brake and one rear brake. If this is what is going on, you need to identify and replace the faulty part. A pull when braking may also have nothing to do with brakes. Bad front tires, or broken belts in a front tire, could cause it.
What causes trouble shooting on the disc brake?
DISC AND DRUM BRAKE TROUBLE SHOOTING 1. EXCESSIVE PEDAL TRAVEL 2. GRABBING OR UNEVEN BRAKING ACTION 3. FRONT DISC BRAKES VERY SENSITIVE TO LIGHT BRAKE APPLICATION 4. EXCESSIVE PEDAL EFFORT 5. RATTLES OR BRAKE SQUEAL 6. BRAKE CHATTER, ROUGHNESS OR PULSATION 7. PREMATURE REAR WHEEL LOCK-UP UNDER HARD BRAKE APPLICATIONS 8. SCRAPING 9.

Why are the brake pins on my car uneven?
The caliper guide pins are essential to the disc brake system. If the caliper pins are not free moving, the brake pads could wear unevenly and you can have premature wear in your brake system.
What causes your brake pads to wear unevenly?
Both can become clogged or damaged, causing uneven wear to your brake pads. With the lines removed from the caliper and put inside of a container, you can depress the brake pedal and watch the fluid. If the brake fluid comes out with just a trickle as the pedal is pushed, remove the hose from the metal line and do the same thing again.

Uneven brake pad wear most commonly occurs as a result of caliper failure. The caliper contains a piston that presses on the brake pads to stop the vehicle. When the driver releases the brake pedal, a seal inside the caliper pulls the piston away from the pad.
What does uneven wear on brake pads mean?
The most common cause of unevenly worn brake pads is what mechanics call Disc Thickness Variation or DTV. Any small difference in the thickness of your discs will cause the brake pad to wear down differently over time. Another cause of uneven brake pad wear is the brake calipers.
