Abstract

A brake booster and related method for its operation for a vehicle, having a master brake cylinder having a first primary piston chamber that is variable using an adjustable first primary piston component, a braking force transmission component, using which at least one driver braking force is transmittable by the adjustable first primary piston component contacted by the braking force transmission component, and an adjustable second primary piston component, the master brake cylinder having a second primary piston chamber that is variable using the adjustable second primary piston component, and the brake booster has a booster force transmission component, using which a booster force from the actuator device is transmittable at least partially to the adjustable second primary piston component contacted by the booster force transmission component, and the braking force transmission component in its force-free initial position is distanced by a first free play from the first primary piston component and/or the booster force transmission component, in its force-free initial position, is distanced by a second free play from the second primary piston component.
