Abstract
A tandem master brake cylinder for a hydraulic motor vehicle brake system, which is impinged upon by a pneumatic brake booster, including at least one piston which is displaceable in a housing and has a plurality of follow-up connections the follow-up connections allowing a hydraulic connection between the pressure chamber and a pressureless follow-up chamber at the start of a braking operation. At least some of the follow-up connections are formed as transverse bores through a wall of at least one piston and are arranged at a same distance relative to the piston edge in a main plane, wherein the overtravel thereof by the sealing collar defines a closure path of the piston. In order to allow a smooth, quiet and yet sufficiently reliable braking initiation, the follow-up connections are arranged in a distributed manner on at least three planes, the planes being arranged at a distance to one another and in parallel to the piston edge.
