Abstract
The invention is a electromechanical locking device for a brake piston of a hydraulically actuated wheel brake. The locking device is disposed at least in some portions in the interior of a hollow-cylindrical brake piston. This interior of the brake piston is filled with hydraulic pressure fluid and in the event of brake actuation is subjected to pressure. The invention includes a filler piece and a coupling element, which reduce the pressure-fluid-filled volume of the brake piston, prevent blocking of the locking device in its terminal positions, and make it possible for the two terminal positions of the locking device to be detected and evaluated by an electronic control unit.
