Abstract
A tandem brake master cylinder comprising a longitudinal bore having two pressure chambers therein each associated with a different one of two pressure pistons, each of the two pressure chambers and its associated one of the two pressure pistons are associated with a different one of two brake circuits. Two parallel inlet sockets are provided in the housing of the tandem master cylinder, each of the two inlet sockets connecting a different one of the two pressure chambers to a brake fluid reservoir. A transverse bore is also provided in the housing of the tandem master cylinder containing a pressure control device for one of the two brake circuits, the control device including a stepped piston and a valve controlled by the stepped piston. The transverse bore intersects a plane containing the axes of the two inlet sockets in an approximate perpendicular manner between the two inlet sockets and beween the longitudinal bore and the reservoir. This construction provides a space-saving arrangement which enables ease of assembly.
