Abstract
A actuator for a brake ort clutch includes a support member which has a flange projecting radially therefrom. An annular piston is slidably and sealingly mounted on the support member on one side of the flange. A pair of disk springs are mounted on the support member on the other side of the flange. A hollow brake-engaging member surrounds the flange, the piston and the disk springs. A first end of the brake-engaging member is coupled to the piston. A second end of the brake-engaging member is coupled to the disk springs and is adapted to engage a wheel brake. The flange, support member, piston and brake-engaging member enclosing a piston chamber. The disk springs are biased to urge the second end of the brake-engaging member away from the flange. Fluid pressure in the piston chamber urges the second end towards the flange.
