PURPOSE: To not hinder the return flow of pressure fluid from wheel brakes to a master cylinder on the termination of a skid control operation. CONSTITUTION: Throttle valves 30, 31, 32, 33 have control inlets 36 which communicate with corresponding wheel brakes 6, 7, 8, 9 respectively. The throttle valves 30, 31, 32, 33 are controlled so that opening springs 34 may be supported by pressure supplied from the wheel brakes 6, 7, 8, 9 to the control inlets 36.
