Abstract (en)
[origin: WO9938740A1] A fluid compensator (100, 225, 325) is provided in a hydraulic control unit (18, 218, 318) of vehicular brake system (10, 200). 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 (18, 218, 318). 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.
