What is a rear backing plate?

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.

Is a backing plate necessary?

You don’t need them. The only thing they do is shield a bit of road dust and debris from reaching the disc pad interface. Remove them and your brake cooling will improve considerably while your inner pad will wear slightly faster.

What does a backing plate do on a car?

Backing Plate Facts MAT Foundry produce more than 10 million brakes and Backing Plates a year. 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.

How much does a backing plate cost?

How much is a backing plate? The cost of brake backing plates may vary depending on inclusions and the vehicle model. Prices for an individual piece or a set may range from $34 to $197.

Are brake backing plates necessary for MoT?

On older vehicles with drum brakes that have components mounted on them, the MoT manual states they should be inspected for ‘presence and security or brake back plates, wheel cylinders and calipers’ and rejected if ‘a brake back plate, wheel cylinder or caliper securing device is lose, missing or excessively …

Can I remove my brake dust shield?

While it might be tempting to remove the brake dust shield to avoid the extra step during brake pad replacement jobs, the risks simply outweigh any perceived benefits.

How does a backing plate get bent?

The backing plate could have bent for a number of reasons. The plate could have failed because it was hung up in the bracket, or the friction material was worn down enough it hurt the integrity of the backing plate.

Can your brakes make noise while driving?

A continuous high-pitched squeal while you’re driving is usually the sound of a built-in wear indicator telling you that it’s time for new brake pads. As the pads wear down and gets thinner, a small metal tab contacts the rotor surface like a needle on a vinyl record to warn you it’s time for new pads.

What is a brake disc shield?

Brake disc dust shields primarily protect your alloy wheels from brake dust, but they can also protect your braking system from road dirt and debris. They can also prevent debris – such as large stones or pebbles – from reaching your brake calipers, adding a layer of protection to you braking system too.

What are brake dust shields for?

A lesser-known but critical component of the braking system is the Brake Dust Shield. This part shields suspension and drivetrain components from the extreme heat generated during braking, while protecting the brake rotors, calipers and pads from environmental elements that can compromise braking performance.

Is the backing plate really necessary?

The backing plate also helps dissipate heat buildup from the friction material. The backing plate must also resist rust and maintain the adhesive bond between the friction material and plate over its entire life. It’s a critical component in every brake system.

How are backing plates work?

A brake backing plate, also called a backing plate, is a steel circular plate that’s attached to the wheel, serving as a foundation for a drum brake. Whenever the brakes are activated, the brake backing plate holds the brake shoes and wheel cylinder in place while they provide the braking force on the drum. The backing plate is a component of the drum-type brake assembly.

What is the purpose of backing plate on brakes?

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. The brake shoes are shaped like the letter C with friction material on the outside curve.

What is a backing plate?

Definition of Backing plate. Backing plate means a license plate which is designed for displaying validation decals, stickers or tabs.
