Working of backing plates
Stamped steel plates upon which the wheel cylinder is mounted and the brakes shoes are attached, metal plated are serve as the foundation for the brakes shoes and other drum plates hard ware which means without backing plates , the brakes have nothing to hold on to. In order for friction to stop the vehicle, the brakes shoes firmly fixed – that’s the particular brakes parts are come in. The brake shoes in drum system have a backing plate to which the friction surface is glued. They are shaped like commas, whereas the brake backing plates found in drum brakes look more like shallow dishes with holes used for fasteners. The function of backing plates is to hold the braking system together so it work properly. With the drum brakes system, each wheel has two curved brakes shoes mounted on the stationary backing plates.
The brakes shoes are shaped like the letter ‘C’ with friction material on the outside curve. They’re attached to either side of the brake plates.
The assembly is, inturn, mounted inside a cast-iron drum that rotates along with the wheel. Spring hold the brake shoe in place so they don’t contact the drum when the brakes aren’t active.
