PCT No. PCT/EP93/03335 Sec. 371 Date Jun. 2, 1995 Sec. 102(e) Date Jun. 2, 1995 PCT Filed Nov. 27, 1993 PCT Pub. No. WO94/12377 PCT Pub. Date Jun. 9, 1994A brake system including electronic anti-lock control (ABS) and electronically controlled brake force distribution (EBV). This brake system has electrically operable hydraulic valves, of which the inlet valves are open in their inactive position. An electronic error monitoring device is provided which responds upon the occurrence of defects or malfunctions and disconnects the control at least in part. The brake system also has control electronics including secondary circuits which remain in function after the error monitoring device has responded, and by which the inlet valves leading to the rear-wheel brakes are actuated and which are provided such that the pressure in the rear-wheel brakes is maintained constant when a limit value of the braking pressure in the master cylinder is exceeded.
