PURPOSE: To reduce the number of solenoid valves so as to simplify the arrangement by providing a pressure-sensitive type inhibition valve, a braking pressure distributor and a restrictor valve in a feed pipe for a rear wheel cylinder, and by connecting a SO valve and the rear wheel cylinder together through the intermediary of a check valve. CONSTITUTION: Wheel, cylinders 1, 2 for front right and rear left wheels are provided in a system of an X-like pipeline so as to feed hydraulic pressure into a pipe line 3 from a master cylinder. The front wheel cylinder 1 is connected through an ABS control inlet valve 5, and the rear wheel cylinder 2 is connected through a pressure-sensitive inhibition valve 7, a braking pressure distributor 8 and a restrictor valve 9. Further, the front wheel cylinder 1 and the rear wheel cylinder 2 are connected together through a check valve 11. When the braking pressure exceeds a predetemtined value, the pressure-sensitive inhibition valve 7 is closed, and accordingly, the braking pressure for the front and rear wheels are controlled only by the front wheel ABS control inlet valve 5. The number of ABS valves can be reduced, thereby it is possible to simplify the entire arrangement.
