  • Actuating piston for a hydraulically and mechanically actuable, spot type disc brake
    Patent number: 6382367
    Abstract: An actuating piston (10) 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 (18) cooperating with a corresponding conical surface of a mechanical actuating device of the disk brake. To make the actuating piston (10) lighter in weight but nevertheless to withstand greater stress, the part of the actuating piston (10) comprising the axial-force-transmitting conical surface (18) consists of steel and the part of the actuating piston (10) 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.
