ABSTRACT:
A brake booster includes a booster piston adapted to be acted upon by the pressure fluid metered through a valve device and displacing a master cylinder piston. A pressure chamber is formed between the booster piston and the master cylinder piston. An additional stepped piston is provided whose larger surface is exposed to the metered pressure fluid and whose smaller surface feeds a predetermined amount of pressure fluid into the pressure chamber so that the brakes are applied after only a short brake pedal travel.
