Abstract
A brake assembly includes a backing plate, a pair of brake shoes slidably mounted on the backing plate, and a wheel cylinder supported on the backing plate between contiguous ends of the shoes. A retaining clip attaches the wheel cylinder to the backing plate. The retaining clip includes a base and a pair of opposed tabs extending from the base. One portion of each tab resiliently and releasably attaches the clip to the backing plate. Another portion of each tab projects into a recess in the wheel cylinder to resiliently and releasably retain the wheel cylinder in a mounted position on the backing plate. The clip and the wheel cylinder are capable of being attached to the backing plate from the same side of the backing plate.

In a drum brake assembly, a wheel cylinder including a stud projecting therefrom, the stud having a pair of recesses extending tangentially through the peripheral surface thereof and including edge portions on oppositely facing walls, a backing plate having a walled aperture therewithin and retaining means for releasably holding the wheel cylinder in a mounted position on the backing plate wherein the stud is received by the aperture, the retaining means comprising:
- an annular base disposed between the wheel cylinder and the backing plate;
- and
- a pair of flexible tabs extending axially away from the base and projecting into the aperture when the retaining means is installed on the backing plate, each tab having one end secured to the base, the opposite end of each tab defining a portion grasping the backing plate, the portion of each tab interconnecting the ends of the tab including a flexible projection comprising a pair of intersecting legs, each recess receiving a corresponding one of the projections and the edge portions of the recess engaging the legs of the corresponding projection to hold the wheel cylinder in the mounted position wherein the recesses are disposed within the backing plate aperture and are facing toward the wall of the backing plate aperture.
