The brake system has an apparatus for traction control having a pressure generator. The pressure generator has a longitudinally displaceable cylinder for receiving brake fluid. The cylinder is connected by means of a valve to a pressure course between a master brake cylinder and a wheel brake cylinder. An actuating element is provided for closing and opening the pressure course to the master brake cylinder as a function of the cylinder position. The actuating element, extending coaxially between the cylinder and the valve comprises a tube and furnishes hydraulic communication between the cylinder and the valve. If excessive drive slip occurs, brake fluid can be positively displaced out of the cylinder by longitudinal displacement thereof, and brake pressure can be generated in the wheel brake cylinder. The actuating element assumes a piston function, which enables a structure of the cylinder having a smaller diameter and a long stroke. This makes for more accurate adjustment of the brake pressure.
