ABSTRACT:
A brake system intended for automotive vehicles provided with a brake pressure transmitter (1) which is linked to the wheel brakes through pressure medium lines, and with sensors (19 to 22, 24) which are responsive to the brake pressure or to the behavior of rotation of the wheels and by means of which the braking effect at the wheels brakes is detectable. Furthermore, separating valves (SO.sub.1, SO.sub.2, SO.sub.3, SO.sub.4, SO.sub.HA ) for shutting off the flow of pressure medium in one switching position are incorporated in the pressure medium paths leading to the wheel brakes. A monitoring circuit (3', 25') to which the sensor signals are transmittable recognizes the failure of one wheel brake and thereupon automatically commutates the separating valve located in the pressure medium path leading to the wheel brake which has failed into a valve position locking the flow of pressure medium.
