PROBLEM TO BE SOLVED: To reduce a sense of stepped braking in antiskid control in regard to a hydraulic brake system generating braking force interlocked with the brake operation of a driver. SOLUTION: Second gate valves 12FL, 12FR are opened (step S61) when both of input valves 9FL, 9FR of the hydraulic brake systems 15L, 15R are closed (judgement of step S50 is "Yes")in holding and reducing hydraulic pressure of a wheel cylinder by driving and controlling an inlet valve and an outlet valve of the hydraulic brake system detecting a rocking tendency out of the hydraulic brake systems 15L, 15R on the front wheel side constituted of the wheel cylinder 3FL (3FR), the inlet valve 9FL (9FR), a reserver 10FL (10FR), the outlet valve 11FL (11FR) and the second gate valve 12FL (12FR).
