Q:

What are the common causes of pulsating car brakes?

A:

The common causes of pulsating car brakes can include the Antibrake System (ABS), a poorly installed wheel or a warped rotor. In fact, pulsating car brakes is a common complaint regarding ABS brakes when the ABS system kicks in. This usually happens when braking on ice, wet roads, or gravel.

Unfortunately, the most common cause of pulsating brakes would be the rotor. The rotor may be warped, but it could also be misaligned. If the wheels were recently installed or have had maintenance work done on them, head back to the auto mechanic and have them double-check to be sure they were installed correctly. If recent work has not been done, the rotor might be warped. This can be caused by sudden braking. Visit a reputable auto mechanic to install a new one if unsure of how to replace it.

    Why do car brakes overheat?

    A:

    Car brakes overheat for various reasons, including as a result of riding the brake and applying excessive force to or overusing the brakes. When brakes overheat on a regular basis, hardened spots can develop on the brake drums or the rotors. These "hot spots" resist friction, causing brake failure.

  • Q:

    Why do car brakes lock up?

    A:

    While there are several reasons brakes lock up, one is a dragging caliper piston. The friction this causes heats brake fluid and increases the pressure in the brake lines, locking a single wheel. Taking the car for a short drive and then checking the wheels for one that is warmer than the rest is a quick way to check for this problem.
