Q:

What could cause brakes to lock up?

A:

Different issues can cause brakes to lock up, including contaminated brake fluid and corroded cylinders. A bad brake hose can also cause this issue.

If the proper amount of fluid does not reach the cylinder or return to the brake fluid reservoir, the brakes can lock up. Since brakes are essential to driving a vehicle safely, brakes that lock up should be checked by a mechanic as soon as possible.

Fixing brakes that lock up depends on the problem. In some cases, the cylinder or pistons need to be replaced, but flushing the brake fluid system can remedy the problem in other instances.

  • 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.

  • Q:

    What causes front brakes to lock up?

    A:

    The most common culprit of locked-up brakes is a malfunction in the master cylinder. The master cylinder is the primary operating system that produces mechanical force from the brake pedal to pistons that operate the drum brakes. The master cylinder system relies on seals leading to the brakes to maintain pressure so the brake system slides to a stop with ease.
