What is a rear backing plate?
Backing Plates are also known as Brake Plates. Backing Plates act as a heat shield for non-metal parts like ball joints which can be damaged from heat caused by braking friction.
What is a backing plate on an axle?
They are pressed plates of steel that provide a support for the brake shoes and wheel cylinder. Those components then combine to provide an outward pressure and braking force on the rotating brake drum, slowing the car down.
Are rear backing plates necessary?
Tasked with the parental duties of the brakes, without these metal backing plates, all braking hardware attached would have nothing to grip on to. Being fixed firmly to the backing plate, brake shoes are provided with the necessary grip and solidity to stop the vehicle via the use of friction.
What does the backing plate hold?
Backing plate—the plate, attached to the axle assembly, holds the components of the drum brake assembly. A backing plate, as shown in Figure 12-2, is stamped steel and has various holes for springs, parking brake cables, and wheel cylinder attachment, and support pads for the shoes.
What is the backing plate on brake pads for?
Your braking system — held together by backing plates — gets to work when you press the brake pedal. The function of backing plates is to hold the braking system together so it can work properly. With drum brake systems, each wheel has two curved brake shoes mounted on the stationary backing plate.
Do brake pads need backing plates?
Without the backing plates working correctly, the entire braking system of a car is bound to fail. Every vehicle contains two curved brake shoes attached to a stationary backing plate on either side of the brake plate. Backing plates provide a firm grip on your car’s braking pads.
Does the backing plate rotate?
Function of Backing Plates The brake shoes are shaped like the letter C with friction material on the outside curve. They’re attached to either side of the brake plate. This assembly is, in turn, mounted inside a cast-iron drum that rotates along with the wheel.
Do you really need brake dust shield?
Unless you have a disc brake system, which cleans itself, the brake dust shield is important to protect the entire system.
How important are backing plates on brake pads?
Do you need the backing plate on brake pads?
Are brake heat shields necessary?
Brake Dust Shields Extend Brake System Lifespan Whether it’s dust from the brake pads, dirt from the road, or other debris, most brake problems from premature wear of components are due to excessive friction during normal use.
Is brake dust shield necessary?
