The booster works by pulling the air out of the booster chamber with a pump creating a low pressure system inside. When the driver steps on the brake pedal, the input rod on the booster is pushed in which lets atmospheric pressure into the booster. This, in turn, pushes the diaphragm toward the master cylinder.

The booster housing is divided into two chambers by a flexible diaphragm. A vacuum hose from the intake manifold on the engine pulls air from both sides of the diaphragm when the engine is running. When the driver steps on the brake pedal, the input rod assembly in the booster moves forward.
