Abstract
During normal operation in which a motor cylinder is operative, when a depressing force cut-off valve is closed, a front wheel is braked by operating a first wheel cylinder by brake fluid pressure generated by the motor cylinder. When there is an abnormality in which the motor cylinder breaks down, the front wheel is braked by supplying, via the opened depressing force cut-off valve, brake fluid pressure generated by a master cylinder operated by a driver's braking operation to the first wheel cylinder, and a rear wheel is braked by supplying the brake fluid pressure to a second wheel cylinder. Thus, since both the front and rear wheels are braked by the brake fluid pressure generated by the master cylinder in case of abnormality, a vehicle can be reliably stopped by a sufficient braking force.
