Brake Backing Plate

A brake backing plate, also known as a brake dust shield or brake splash shield, is a metal plate that is located behind the brake rotor or drum. Its main purpose is to protect the braking system components from debris, such as dirt, rocks, and water, that can cause damage or reduce the effectiveness of the brakes.

The backing plate is typically made of steel or aluminum and is mounted to the wheel hub or axle flange. It acts as a barrier between the brake components and the outside environment, preventing debris from entering and interfering with the operation of the brakes.

In addition to providing protection, the backing plate also serves as a mounting point for various brake system components, such as the brake caliper, brake pads, and brake shoes. It helps to keep these components in place and properly aligned, ensuring that the brakes function correctly.

Overall, the brake backing plate plays a crucial role in maintaining the performance and longevity of the braking system by protecting it from external elements and providing structural support.
