One of the most common sustenance jobs performed on any vehicle isreplacing the brakes . When they begin to feel a mo squishy or begin to fink , something must be done . mayhap you’re able to swap out brake shoe yourself , or maybe you require to take it to the store to get the job done . But what ’s book all those pasture brake parts together ? If you ’re talking about drum brake system , the unappreciated heroes are the brake backup home .

Brake plate are , according to the automotive glossary at AutoZone.com , " Stamped sword plate upon which the cycle piston chamber is mounted and the bracken skid are attached ; metallic element plates that serve as the foundation for the bracken shoes and other metal drum brake hardware " [ beginning : AutoZone ] .

Which means that without the backing plate , the brakes would have nothing to bind on to . In order for friction tostop the fomite , the bracken shoe must be firmly fixed – that ’s where this particular Pteridium aquilinum part comes in .

­There can be some confusion around the term " backing denture , " as it can also refer to a part used in disc brake systems . The brake shoes in those systems have a backing plate to which the detrition surface is glued or concentrate . They are work like commas , whereas the brake backing plate found in drum brakes look more like shallow dishes with holes used for fasteners .

­Now that we know where the financial backing plate is located and what it attend like , let ’s see a footling further at the function of backing plates .

Function of Backing Plates

The occasion of backing scale is to harbour the braking scheme together so it can work properly . With drum brake scheme , each cycle has two kink brake shoes climb on the stationary backing collection plate . The brake shoes are shaped like the varsity letter 100 with rubbing material on the outside curve . They ’re attached to either side of the brake plate . This assembly is , in turn , mount inside a shape - branding iron tympan that rotates along with the bicycle . Springs moderate the bracken shoes in place so they do n’t get in touch with the drum when the brake system are n’t active .

When the number one wood push down on the brake pedal point , this places pressure level on the hydraulic fluid in the brake assembly line . At the top of the backing plate is a wheel cylinder containing two pistons , one at either end . The insistency from the brake fluid enters the wheel piston chamber and force the outflow - loaded pistons to move outward from the wheel cylinder , bear on the brake shoes against the inside of the brake drum .

The detrition material on the outside edge of the brake shoe coming into physical contact with the inner surface of the brake drum is what stops the cable car . But without the constancy and routine of brake plates keeping all of these brake parts in place and taking the brunt of the braking force , none of it would put to work .
