<p>PROBLEM TO BE SOLVED: To provide a vehicular brake hydraulic pressure control device in which output hydraulic pressure of a master-cylinder is not absorbed by a reservoir during brake operation even when a leakage fault occurs in a suction valve.SOLUTION: Suction valves 16 are disposed between a suction chamber 46 continued to a suction port of hydraulic pumps 8a and 8b and suction passages 15a and 15b. A check valve 18 is disposed at a communication passage 49 through which the suction chamber 46 is communicated with a liquid storage chamber 34 of a reservoir 9 to block liquid current from the suction chamber 46 side to the liquid storage chamber 34 side and to allow liquid current in a direction opposite thereto. Valve opening drive means 32, the check valve 18, and the suction valve 16 are, when the valve opening drive means 32 is activated, interlocked to sequentially open the check valve 18 and the suction valve 16.</p> |
