Abstract: A brake is disclosed comprising an annular cylindrical braking member with brake shoes respectively on the inside and outside of the braking member which are straddled by a C-shaped caliper member. The caliper member is pivotally and slidably mounted by a composite mounting assembly comprised of a pivot pin and a tubular bracing member received snugly thereon. The pivot pin acts in tension between opposed leg portions of fixed support while the bracing member acts in compression. A sealing pad or cap is disposed at each of the ends of the passageway in the caliper member through which the mounting assembly extends for providing fluid tightness thereat.

Abstract: A C-shaped caliper member straddles the hollow cylindrical braking member, a hydraulic actuator and brake shoes on the respective sides of the braking member. To axially retain the caliper member two circumferential, laterally projecting shoulders are provided on the end of the backing plate of at least one of the brake shoe remote from but facing the intermediate portion of the caliper member abutting against flats on the fixed support of the brake, an axial bearing surface extending from the opposite end of the backing plate, and an axial bearing surface on the caliper member or a part associated therewith axially beyond the first mentioned axially bearing surface, the axial bearing surfaces being cooperable with a removable retaining pin.
