Abstract
An actuating piston ( ) of a hydraulically and mechanically actuable, spot-type disk brake for motor vehicles, which is disposed in a sealing and displaceable manner in a cylinder bore of the disk brake is provided with an axial-force-transmitting conical surface ( ) cooperating with a corresponding conical surface of a mechanical actuating device of the disk brake. To make the actuating piston ( ) lighter in weight but nevertheless to withstand greater stress, the part of the actuating piston ( ) comprising the axial-force-transmitting conical surface ( ) consists of steel and the part of the actuating piston ( ) cooperating with the cylinder bore of the disk brake is made of light metal or of plastics material, said components of the actuating piston being constructed as a single-piece composite component.
