Abstract: An electric brake system includes a reservoir, a master cylinder including first and second hydraulic ports, a simulation device providing reaction force in response to foot force applied to a brake pedal, a hydraulic-pressure supply device, a hydraulic-pressure control unit, and an electronic control unit (ECU). The hydraulic-pressure supply device converts rotational force of a motor into rectilinear motion upon receiving an electric signal from the pedal displacement sensor, and moves a double-acting piston designed to perform reciprocating motion within a hydraulic cylinder. The double-acting piston moves in both directions such that the first hydraulic chamber located at one side or the second hydraulic chamber located at the other side are pressed, resulting in formation of hydraulic pressure.
