Can a bad brake booster cause brakes to stick?

But if the booster is getting stuck in its boost mode, it will continue to apply force to the brakes even after you release the pedal. And it’s not unusual for a faulty booster to stay on after a full stop, and then release itself. Then, the next time your brakes lock up, pull over and disconnect that vacuum hose.

Why would my brake pedal go all the way to the floor?

If that happens, the fluid can’t get back into the master cylinder after you take your foot off the brake pedal. The result is brake caliper stickiness. A caliper piston that doesn’t fit right in the caliper housing could cause the piston to bind under braking or with the release of the brake pedal.

What are the symptoms of a brake caliper sticking?
