A brake support assembly to be mounted on a vehicle axle housing for supporting a brake shoe assembly and an actuator therefor comprising a backing plate adapted to be fixedly mounted on a vehicle axle housing and two anchoring plates removably attached to the backing plate for pivotally supporting the brake assembly. Each anchoring plate includes projections which correspond to bores in the backing plate for positioning the anchoring plate at a predetermined position on the backing plate whereby the anchoring plate may be removed and replaced while maintaining a constant positioning of the brake assembly. In a first embodiment, the anchoring plate includes integral projections extending therefrom. In a second embodiment, the anchoring plate includes a tapered bore extending therethrough for supporting a pin. The pin extends from the plate defining the projection which corresponds with the bore in the backing plate. The backing plate also includes a pocket for retaining a spherical bushing which provides a low friction support for the actuator shaft whereby the bushing allows for small amounts of variation in the alignment of the actuator shaft.
