ABSTRACT:
A hydraulic brake booster is provided which actuates a master cylinder by a hydraulic power pressure supplied from a power source in response to an input rod connected to a brake pedal. The arrangement includes a housing connected to the master cylinder, a power piston slidably disposed in a boost chamber which defined in the housing and transmitting a boost force which is generated in response to the input rod. A hydraulic pressure control valve is provided which has a valve body moved between a power position communicated with the power source and an initial position communicated with a reservoir in the boost chamber on an axis extending substantially in parallel with a sliding axis of the power piston. A control lever engages with the valve body of the hydraulic pressure control valve at its one end and engages with the power piston at its other end. A support lever is pivotally connected with the input rod at one end and a support member installed to the housing pivotally movable and regulating at least the initial position of the valve body of the hydraulic pressure control valve through the one end of the control lever.
