How is a brake booster different from a master cylinder?
While the master cylinder’s diameter is already smaller than that of the caliper pistons, the force required to compress it is still great. The brake booster works on the principle of vacuum differentials to aid in pushing the master cylinder. On one side, vacuum is sucked from the engine’s intake.
What kind of brake booster does a school bus use?
1980 Training filmstrip for the HydroVac brake booster system used on GM’s large medium duty and school busses.

Is there a vacuum leak in the booster?
Make sure everything that attaches to the booster is tightened correctly and seals are good – if any (I don’t know your car). Because there is a change in the idle when you press the brake pedal, there absolutely is a vacuum leak somewhere. Very unlikely to be the booster itself.
How does a power brake booster work on a car?
At idle, a valve in the diaphragm allows vacuum to be passed through the diaphragm, so that vacuum balances both sides. When you depress the brakes, that valve moves, sealing off the vacuum side, while allowing filtered atmospheric air to enter the booster from the brake pedal side.
