MASTER BRAKE CYLINDER FOR A HYDRAULIC VEHICLE BRAKE SYSTEM

A hydraulic block of a slip regulation system of a hydraulic external force vehicle brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a master brake cylinder piston on an end stop when the master brake cylinder is released, in particular when there is a sudden release, for example when the driver's foot slips off the brake pedal, the present invention provides a hydraulic return flow damper that is integrated in the master brake cylinder piston.
