A control unit 10 controls brake forces of brake systems of a pair of brake operation elements L1, L2 operated independently to perform an anti-lock brake control for eliminating a locked state of a wheel. The control unit 10 applies the brake force to one of the wheel brakes B1, B2 of the brake system which differs from the brake system of the operated brake operation element when the brake operation elements L1, L2 is operated. When one or both of the brake operation elements L1, L2 are operated and so the wheel likely falls in a locked state, the control unit 10 performs an anti-lock brake control on the brake system of the wheel likely falling in the locked state and also performs a brake force application control on the other brake system which is different from the brake system of the wheel likely falling in the locked state.
