Abstract: In the present invention, a brake device is equipped with: differential pressure control valves; pressure adjusting units which are connected to the differential pressure control valves through liquid passages; and a control device which controls the WC pressure Pwc in wheel cylinders by operating the differential pressure control valves and the pressure adjusting units. When predetermined suppression control permission conditions are satisfied while both the supply pumps of the pressure adjusting units and the differential pressure control valves are in operation, the control device performs self-excited vibration suppression control over the differential pressure control valves, the self-excited vibration suppression control being carried out in such a manner that a valve element separated from a valve seat is caused to abut on the valve seat, and, upon abutting on the valve seat, the valve element is separated from the valve seat.
