Re: brake pedal squeak 2000 crown vic
Probably just the booster. One good test is to pump the pedal a few times with the engine off. Then hold the pedal down and start the car. The pedal will drop some to show that the booster is okay. If ti barely moves, your booster needs replacement for sure. There could be other problems with the booster that could cause a noise by something dragging inside. The master cylinder doesn't usually cause what you're explaining. Maybe the pedal bushings themselves.
