PROBLEM TO BE SOLVED: To inhibit deceleration from stagnating and prevent brake feeling from becoming deteriorated when a port of a master reservoir is closed.SOLUTION: A pressurized extension stroke is set. Even when an M/C stroke exceeds an invalid stroke, a differential pressure indication value to first and second differential pressure control valves 16, 36 is continuously increased within the pressurized extension stroke so that pump pressurization is also continued. By this way, a brake fluid can be supplied to the side of a W/C, and W/C pressure can be also increased continuously while a pressure-adjusting reservoirs 20, 40 are filled with the brake fluid. Accordingly, deceleration can be inhibited from stagnating, and brake feeling can be prevented from becoming deteriorated when a port 13f of a master reservoir 13e is closed. |
