A vehicle brake control system comprising a master cylinder, a wheel cylinder of a road wheel, a brake circuit connecting the master cylinder and the wheel cylinder, a pressure control valve installed in the brake circuit, a reservoir into which a brake fluid is led from the wheel cylinder when the pressure control valve operates to reduce the hydraulic pressure of the wheel cylinder, an electric fluid pump that, upon energization thereof, pumps the brake fluid from the reservoir to the brake circuit at a position upstream of the pressure control valve, an inlet circuit connecting the inlet opening of the pump to the master cylinder, an inside gate valve installed in the inlet circuit, and a control unit that controls the pressure control valve, the inlet gate valve and the electric fluid pump and carries out a predetermined brake control to adjust the hydraulic pressure of the wheel cylinder by operating the pressure control valve. The control unit is configured to carry out a flow back control after completion of the predetermined brake control. The flow back control is a control wherein the inside gate valve is kept open having the electric fluid pump kept de-energized.
