A disc brake mechanism, including an integral mechanical parking brake assembly and having automatic wear adjustment features, is disclosed. The adjusting mechanism comprises an axial thrust screw having one end exposed to atmospheric pressure to create an axial hydraulic differential pressure acting thereacross. An adjusting nut is threadably received on the thrust screw and normally engages a hydraulic actuating piston such that the adjusting nut is free to rotate with respect to the thrust screw and piston. Hydraulic pressures acting upon the thrust s...
In a mechanically actuated brake assembly having a rotary ball cam actuating mechanism including a first cam plate and an opposing second cam plate, each cam plate having a multiplicity of oppositely corresponding ball ramp surfaces, a corresponding number of balls positioned between and received within said ball ramp surfaces whereby rotation of said first cam plate causes said balls to roll along said ball ramp surfaces thereby effecting axial separtion of said cam plates by an amount proportional to the angular rotation of said first cam plate, the im...
