ABSTRACT:
A friction brake is for a wheel which is mounted for rotation on an axle spindle and includes a backing plate mounted about an inward portion of the spindle. An annular hydraulic cylinder is removably secured to the backing plate and receives therein, in sliding engagement therewith, an annular piston which combine to form a hydraulic actuating device. A housing is secured to the backing plate for sealed encirclement of the wheel to define a cooling fluid chamber therebetween. An alternating arrangement of non-rotating discs, those mounted relative to the housing and backing plate, and rotating discs mounted relative to the hub are disposed within the cooling chamber between the housing and the actuating device. The selective introduction of hydraulic fluid to the actuating device applies force to the discs as they are entrapped against the housing to produce frictional contact therebetween to prevent rotation of the wheel.
