Abstract

PURPOSE: To make appropriate the distribution of hydraulic pressure to the front and rear brakes, by installing between a master cylinder and rear wheel brakes a hydraulic control valve unit consisting of an inertial cut-off valve and a stepped piston.
CONSTITUTION: The hydraulic control valve unit 100 having a casing 20, wherein a ball 21, the cut-off valve 23 and the stepped piston 28 are arranged, is installed between the tandem master cylinder 11 and the rear wheel brakes 14. When a predetermined deceleration occurs in braking operation of unloaded vehicle, the ball 21 rolls and a valve body 26 comes into contact with an oblique inside wall 24a against a spring 27 to cut off the master cylinder pressure supply to the rear wheel brades 14. As a result, excessive braking force is not caused, thereby preventing the wheels from being locked. As for loaded vehicle, the stepped piston 28 moves left and the ball 21 is held from rolling. Therefore, the cut-off valve 23 is kept open, thereby supplying sufficient braking pressure to the rear wheel brakes 14
