A hydraulic brake system includes: a plurality of hydraulic brakes respectively provided for a plurality of wheels of a vehicle, each of which is configured to reduce rotation of a corresponding one of the wheels by a hydraulic pressure in a hydraulic-pressure chamber of a wheel cylinder; and a plurality of electric cylinder devices each of which is provided for one or more of the plurality of hydraulic brakes. Each electric cylinder device includes: a housing; a piston fluid-tightly and slidably disposed in the housing; an electric motor as a drive source; a rotation-linear motion converting mechanism configured to convert a rotational motion of the electric motor to a linear motion of the piston; and a volume change chamber disposed forward of the piston and connected to the hydraulic-pressure chamber of the wheel cylinder of each of the one or more of the plurality of hydraulic brakes.
