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 to generate hydraulic pressure by pressing a first hydraulic chamber provided in one end thereof, and moves in another direction to generate hydraulic pressure by pressing a second hydraulic chamber provided in the other end thereof.
