Abstract
A vehicular hydraulic brake system with an anti-locking arrangement, wherein first valve devices (10, 16, 17, 20, 27, 28, 29, 30) are interposed between a master cylinder (3) and brake-actuating member (11, 12, 13, 14) which valve allow interruption of the supply of pressure fluid to the brake-actuating members (11, 12, 13, 14) and to removal of pressure fluid from brake-actuating members (11, 12, 13, 14). The first valve devices (10, 16, 17, 20, 27, 28, 29, 30) are controllable by a slip-monitoring electronics (18) as a function of the wheel rotational behavior, and provision is made of a device for ensuring availability of a minimum stroke of the master cylinder (3) as a reserve. A shut-off valve (9, 15) is interposed between the master cylinder (3) and the first valve devices (10, 16, 17, 20, 27, 28, 29, 30), and the connection between shut-off valve (9, 15) and the first valve devices is connectible by way of second valve (24, 25) to an auxiliary pressure source (22) which supplies pressure proportional to the pedal force (F).
