Brake boosters are used only on power brakes, not manual brakes. The booster's function is to give more braking power with minimal pressure on the brake pedal. If the booster is not working properly, you will still have brakes, but the brake pedal will be very hard to push.
A brake booster is what gives power brakes their power. It works on vacuum from the engine. The booster pushes on the master cylinder with the pressure applied to the booster by stepping on the brake. If the engine is off, it cannot get vacuum, therefore the brakes will be hard when the engine is off. This is noticeable when pushing a stalled vehicle and stepping on the brake.
The brake booster is made of five parts: the booster piston, body, booster return spring, control valve and reaction valve. The body has two chambers--the variable pressure chamber and constant pressure chamber--separated by a diaphragm.
Types
The brake boosters 's size and whether it has a single or more than one diaphragm depend on the year, make and model of the vehicle. When ordering a new booster, tell the auto parts store or dealer the year, make and model of your vehicle, and they will give you the correct one.
