  • Patent number: 9283943
    Abstract: A brake apparatus, which is configured to generate a hydraulic pressure in a master cylinder, sets a control position of a primary piston. According to a movement of an input piston in response to an operation of a brake pedal, the brake apparatus generates a hydraulic pressure in a primary chamber of the master cylinder by driving the primary piston by an electric motor to supply brake fluid to a brake caliper, thereby exerting a brake effect. The brake apparatus sets a first control position where the primary chamber is out of communication with a reservoir, and a second control position where the primary chamber is in communication with the reservoir as a holding position of the primary piston when no brake is applied. Then, the brake apparatus appropriately switches the holding position of the piston between the first control position and the second control position.
