Abstract
A hydraulic brake system includes a master cylinder forming a braking hydraulic pressure and wheel brakes receiving the braking hydraulic pressure and exerting a braking force. A first hydraulic circuit controls an oil pressure transmission by connecting a first port of the master cylinder and two wheel brakes, and a second hydraulic circuit controls the oil pressure transmission by connecting a second port of the master cylinder and remaining wheel brakes. A hydraulic block communicates main passages of the first and second hydraulic circuits with each other by a communication passage having one side opened. Pumps are mounted on the main passages to discharge oil toward the wheel brake or the master cylinder, and an orifice is mounted on each of the other side of the main passages. A damper assembly is coupled to the communication passage provided between an output port side of the pump and the orifice.
