Abstract
A vehicle brake hydraulic control apparatus includes a reservoir, a hydraulic pressure pump, an orifice, a damper and a one-way valve. The reservoir absorbs an excess brake hydraulic pressure of a wheel brake. The hydraulic pressure pump suctions brake fluid absorbed by the reservoir and returns the suctioned brake fluid to a master cylinder through a return line. The orifice is provided in the return line. The damper is connected to the return line between the orifice and the hydraulic pressure pump and damps discharge pressure pulsation of the hydraulic pressure pump. The one-way valve is provided in the return line between the damper and the orifice and prevents a hydraulic flow from an orifice side to a damper side.
