摘要： A boost state of an upstream side brake fluid pressure producing device that boosts a braking operation force of a braking operation member and produces a fluid pressure in a master cylinder is adjusted according to a refluxing brake fluid characteristic of brake fluid that refluxes to the master cylinderby a pressure decrease control and an outflowing brake fluid characteristic of the brake fluid that flows out of the master cylinder into a wheel cylinder by a pressure increase control, and variation of the braking operation member is suppressed. It is therefore possible to suppress an occurrence of vibration and noise of the brake pedal during the ABS control.
