Cadillac Brake Booster

The modern Cadillac brake booster is an ingenious device that operates using something that your engine generates whenever it's running: vacuum.

The car parts takes engine vacuum via a rubber hose that runs from the intake manifold, and the brake booster uses that vacuum to amplify the pressure you put on the pedal.

A light application of the brakes is translated by the factory parts into significantly more pressure on the brake master cylinder, ensuring that your car stops quickly.

So what happens to the Cadillac brake booster if your car stalls, resulting in a loss of engine vacuum?
