In a tandem master cylinder for a vehicle hydraulic brake system having a push-rod piston designed as stepped piston and an intermediate piston designed as stepped piston both pistons being aligned in a stepped bore of the cylinder housing for the purpose of obtaining a particularly short and compact design. The working cylinder communicates with the connecting bore of the one brake circuit provided in the large-diameter step of the intermediate piston, while the small-diameter step of the intermediate piston fits in the working cylinder formed by the small-diameter step of the stepped bore so that the working cylinder is in communication with the other brake circuit via the connecting bore.
