Abstract
A hydraulic brake control system for a vehicle includes a return line for reducing a pressure built up in a wheel cylinder. The return line includes therein a switching valve for opening and blocking the return line. The return line further includes therein cylinders each having therein a piston for defining a piston chamber therein. Each piston has a first state where a brake fluid flowing from the wheel cylinder via the switching valve is allowed to flow into the piston chamber, and a second state where the brake fluid is allowed to be discharged from the piston chamber so as to be returned to a master cylinder. An operation control mechanism is provided for controlling the pistons into the first states and the second states, respectively, at different timings from each other in turn.
