PROBLEM TO BE SOLVED: To prevent degradation of a braking feeling attributable to the fact that a brake pedal is sucked into an M/C due to suction of a brake fluid from the M/C.SOLUTION: When ports 13f, 13g, and 13h are blocked, if W/Cs 14, 15, 34, and 35 are pressurized by sucking a brake fluid from an M/C 13 through driving of pumps, brake fluid feed quantity increase control is implemented. That is, in a suction state in which suction of a brake pedal 11 is performed, or in a suction predicted state in which the suction is predicted, compared with in any other state, a feed quantity of the brake fluid by pumps 19 and 39 is increased. Accordingly, master pistons 13a and 13b are turned down, and suction of the brake fluid from a master reservoir 13e via the M/C 13 is enabled. Therefore, the brake pedal 11 can be prevented from being sucked into the M/C 13, and degradation of a braking feeling can be prevented. |
