Abstract: The invention relates to a cold-formed steel brake piston 1 for a motor vehicle partial-pad disc brake brake pad with a thin-walled structure as a cup open at one end and comprising a base 2 and a wall 3 with a radially outwardly impressed groove 6 in the wall 3 and with a radially inwardly impressed wall projection 7. The invention has the object of providing a further improved stable steel brake piston construction with an improved interface which can be used flexibly and cost-effectively for both large-bore and small-bore steel brake pistons 1. This object is accomplished by making the wall 3 with at least one groove 14 and at least one land 15 at a distance from wall projection 7 profiled in such a way that wall 3 has wall surface areas of varying thickness which are spaced apart from each other in the circumferential direction with a spacing V.

Abstract: A double cup-shaped piston for a disc brake including an electromechanical parking brake device. An aspect of the invention permits an improved compromise between easier operability, rationalized component logistics in piston production, reduced hydraulic volume uptake in cooperation with the wheel brake periphery, and enhanced fatigue strength under maximum collective stress, in particular for heavy-duty applications of a disc brake with an electromechanical parking brake device. The problem is solved by the presence of a piston wall, which is provided, on the one hand, to sit with a free edge on a rear plate of a friction lining, and wherein the piston, on the other hand, includes an integral dome which forms an open receptacle for an actuator arranged diametrically to the edge of the piston.

Abstract: Methods and corresponding control devices for releasing an electric actuator in a reliable manner, such as an electric parking brake in particular, in a motor vehicle brake system. The aim of the invention is to provide an improved function and architecture which helps prevent the disadvantages of open-loop control systems when using a rationalized sensor system, thereby obviating closed-loop control systems. This is achieved by a release method and a corresponding electronic control unit which obtains an especially modulated change in the power requirement during the release process upon impacting the quasi-elastic release end stop of the electric actuating unit such that the change is fed back, the change being detected in order to be used as information for a power interruption or a termination of the power supply to the electric actuating unit.
