ブ。 A hydraulic pressure chamber into which the hydraulic pressure of the main side master cylinder is introduced is provided in front of the piston provided in the cylinder hole, and a valve is provided to open and close a passage between the hydraulic pressure chamber and the main side master cylinder. The valve is controlled by movement of the piston by hydraulic pressure of a sub-side master cylinder applied to the rear surface of the piston, and a spring is disposed in the hydraulic pressure chamber between the piston and the bottom surface of the cylinder hole. When the sub-side master cylinder is not in operation, a valve lift is formed between the valve and the end face of the cylinder hole, and the hydraulic pressure generated in the hydraulic pressure chamber by the operation of the main-side master cylinder and the sub-side master cylinder is used to control the wheel cylinder. In the brake system, a spring is interposed between the back surface of the piston and the bottom surface of the cylinder hole to form a clearance between the back end surface of the piston and the bottom surface of the cylinder hole. valve.
