A vacuum brake booster provides power assist to the brake system. As anyone who has experience a booster failure knows, the booster greatly reduces the effort required to stop the vehicle. Most brake boosters, have two or more chambers, divided by flexible diaphragms. The chamber is normally steel and the diaphragm is usually some form of rubber. They attach a metal push rod to the diaphragms and it moves with them. Vacuum, usually supplied by the engine and atmospheric pressure combine to provide the assistance during braking.

A vacuum servo also known as a power booster or power brake unit uses a vacuum to multiply the drivers pedal effort and apply that effort to the master cylinder.The vacuum can be generated in two distinct methods, dependent on the type of internal combustion engine, or other motive force (as in electric vehicles). In the manifold vacuum is used, whereas in turbo charged, diesel engines, and electric/hybrid vehicles a separate vacuum pump is used (or in certain high altitude places, naturally-aspirated vehicles are not capable of producing enough vacuum for the booster. The vacuum pump can be driven mechanically (from the engine) or by means of an electric motor. The vacuum is transferred to the servo along non-collapsible vacuum lines, and is stored in the servo by using a non-return valve.
