PROBLEM TO BE SOLVED: To surely supply a hydraulic pressure from a master cylinder to a wheel brake by interposing a hydraulic responding valve device in a hydraulic passage for connecting the master cylinder to the wheel brake. SOLUTION: A hydraulic responding valve device 19 is interposed in a hydraulic passage 20 for connecting a master cylinder 16 to a wheel brake 12. The hydraulic responding valve device 19 allows the master cylinder 16 to communicate with the wheel brake 12 when the master cylinder hydraulic pressure is less than a set value. When the master cylinder hydraulic pressure rises the set value or more by the operation of a brake pedal 13, the hydraulic responding valve device 19 allows only the brake fluid passing from the master cylinder 16 side to the wheel brake 12 side. According to this, a hydraulic pressure can be supplied from the master cylinder 16 to the wheel brake 12 through the hydraulic responding valve 19. |
