Abstract
A slip-controlled hydraulic brake system with improved operational reliability during the slip control phase of operation has a master cylinder having shortened overall axial length. The master cylinder includes a valve-opening mechanism of one central control valve supported on the bottom of the longitudinal bore of the master cylinder, and the valve-opening mechanism of another central control valve supported on the secondary piston wherein during a slip control action, in the presence of a predetermined travel of the pistons of the master cylinder, a force component is generated that increases the reliability of the opening of the central control valves.
