ABSTRACT:
A drum brake assembly for a vehicle wheel includes an axle housing flange extending upwardly and provided with an opening through which the wheel cylinder hydraulic line input and bleed fittings extend. A thin wall backing plate is secured to the flange and supports the wheel cylinder but does not take brake torque. The anchor pin is assembled through the backing plate directly to the flange, also fastening the backing plate to the flange at this point. This provides a precise anchor pin location with the anchor pin also acting as a braking unit mounting bolt, taking the place of two mounting bolts in common usage. A pair of backing plate mounting bolts generally opposite the anchor pin also secure the backing plate to the flange. The wheel cylinder is retained on the backing plate by a wire clip instead of the commonly used mounting bolts. The brake shoes, springs and other control elements are mounted on the backing plate in the usual manner.
