Brake shoe mounting assembly

摘要

A brake shoe mounting assembly is provided for a brake mechanism mounted within an axle housing located on the inboard side of a wheel mechanism and having an arcuate brake drum assembly mounted therein. The mounting assembly includes an arcuate brake shoe disposed in the housing for confronting the brake drum assembly and an actuator apparatus mounted in the housing and being engageable with the brake shoe and responsive to engagement of the brake pedal for expanding the brake shoe into frictional engagement with the brake drum. The actuator and the brake shoe are interconnected for sliding and in particular, a slotted beam assembly is attached to either one of the actuator and the brake shoe and an insertion assembly is attached to the other. The slotted assembly extends in an inboard direction and slidably receives the insertion assembly. The insertion assembly is releasably fastened within the slotted assembly to lock together the actuator and brake shoe and the slotted and insertion assemblies are released to enable selective removal of the brake shoe from and insertion of the brake shoe into the housing through the inboard end.
