  • Hydraulic control unit with fluid compensator to accommodate travel of master cylinder piston
    Patent number: 6375279
    Abstract: A fluid compensator is provided in a hydraulic control unit of vehicular brake system. The fluid compensator permits additional displacement of a master cylinder piston during anti-lock braking events only by storing fluid in the hydraulic control unit. The additional displacement moves a seal mounted on the master cylinder piston away from a compensator port orifice, thereby preventing repeated “nibbling” of the seal which can cause premature seal failure.
