ABSTRACT:
In a hydraulic braking pressure control system for a rear wheel brake wherein a control piston normally works to provide a hydraulic braking pressure control by cooperation with a cut-off valve interposed between an input chamber leading to a master cylinder and an output chamber leading to a wheel cylinder of the brake, the cut-off valve has a valve seat piston whose pressure-receiving area facing the output chamber is larger than the pressure-receiving area facing the output chamber. This ensures that opening and closing of the cut-off valve can be repeated in accordance with the output pressure from the master cylinder, so that the output pressure from the master cylinder can be reduced and applied to the brake wheel cylinder. When the control hydraulic pressure is lost, the control piston and sleeve can be moved in a direction to increase the volume of the output chamber thereby to close the lock valve and tightly close a control chamber between the control piston and sleeve, while restraining by a stopper the movement of the cut-off valve following in a closing direction of the control piston and sleeve. This makes it possible to insure a hydraulic braking pressure applied to the brake wheel cylinder.
