1. An automotive brake fluid control apparatus, comprising:

  • a reservoir to accumulate brake fluid expelled from a wheel cylinder via a pressure-control valve; and

    a pump to boost pressure of brake fluid accumulated in said reservoir and supply said brake fluid to a wheel-cylinder side via said pressure-control valve, wherein said pump is a self-suction pump that takes in brake fluid from a master-cylinder side thereof;

    pump operating means for causing said pump to start operation at a predetermined timing before initiating regulation of brake fluid pressure applied to said wheel cylinder by said pressure-control valve, to take in brake fluid from said master-cylinder side; and

    communicating path forming means for defining a path wherein a discharge side and an intake side of said pump are communicated so that brake fluid discharged from said pump circulates in said communicating path upon operation of said pump by said pump operating means.
