A hydraulic brake system for braking a vehicle, including a master cylinder device having a fluid-flow permission mechanism that permits a flow of a working fluid between an inter-piston chamber and a low-pressure source, wherein, when a pressure of the working fluid to be supplied to a brake device exceeds a set pressure upon advancing in association with an advancing movement of a brake operation member, a closing and opening mechanism for hermetically closing the inter-piston chamber and opening an opposing chamber to the low-pressure source is controlled so as to hermetically close the inter-piston chamber, while, when the pressure of the working fluid becomes lower than a set pressure upon retracting in association with a retracting movement of the brake operation member, the fluid-flow permission mechanism is controlled so as to permit the flow of the working fluid between the inter-piston chamber and the low-pressure source.
