Car part From Wikipedia, the free encyclopedia

A vacuum servo (also called a brake booster, power booster, or power brake unit) is a component used on motor vehicles in their braking system, to provide assistance to the driver by decreasing the braking effort. It uses a vacuum, usually supplied by the engine, to multiply the driver's pedal effort and apply that effort to the master cylinder.[1]

Because the servo depends on the vacuum supplied by a running engine, a check valve is typically used in the vacuum line to maintain residual vacuum without engine support, allowing limited use even after parking.
The system was invented by Albert Dewandre[2] who, together variously with Bosch and Clayton-Dewandre Ltd. took out further patents as it was refined.[3]
