A vacuum system that increases brake pressure, thereby reducing the actual pedal pressure required to properly apply the brakes.

Device to mechanically increase the braking effort and reduce the required pedal pressure.

a metal bridge that connects the outer ends of the two cantilever bosses, holding them in position and greatly reducing their tendency to flex under load

A vacuum-operated mechanical device that multiplies the manual force exerted when braking, thereby reducing the actual pedal pressure required to properly apply the brakes.

If your car has power brakes, a brake booster is located between the brake pedal and the master cylinder to increase the force applied to the brakes. There are two common types

A device that uses a supplementary power source to reduce pedal force in a hydraulic brake system.
