ABSTRACT:
A brake system comprising a hydraulic braking pressure generator (1) to which are connected the brake wheels (6-9); an auxiliary pressure supply system including a hydraulic pump (10) and an auxiliary pressure control valve (12) causing an auxiliary-pressure proportional to the pedal force (F). Pressure-controlled multidirectional valves (27,28) are provided establishing a connection between either the braking pressure generator or the auxiliary pressure supply system and the wheel brakes (6-9). The pressure-controlled multidirectional valves (27,28) are structurally combined with a switching mechanism (41,42) to signal the operating condition of the brake system, in particular, a pressure breakdown or defective conditions of the valves. A connection is established, via one of the pressure-controlled multidirectional valves (27), between the pedal travel simulator and the braking pressure generator (1). The brake system can be applied to a slip-controlled system.
