Often referred to as a brake dust shield or brake disc splash guard, the backing plate sits behind the brake disc and provides a protective barrier between the braking system and contaminants thrown up from the road. It also helps guide cooling airflow around the brake assembly, contributing to consistent braking performance.
As these plates are mounted underneath the vehicle, they are frequently exposed to moisture, road salt, stone impacts and corrosion. Replacing damaged or rusted backing plates helps maintain brake system protection while restoring the appearance of the suspension and braking assembly.
What Does a Brake Disc Backing Plate Do?
The brake disc backing plate performs several important functions within the braking system.
Its primary roles include:
- Protecting the brake disc from road debris
- Shielding brake components from dirt and water
- Helping manage brake cooling airflow
- Reducing contamination around the brake assembly
- Protecting wheel bearing components
- Supporting long-term brake system reliability
- Maintaining factory brake system design
Although often overlooked, the backing plate contributes to the overall durability and effectiveness of the braking system.
Why Do Brake Disc Backing Plates Fail?
Brake backing plates are constantly exposed to harsh operating conditions beneath the vehicle.
Common causes of failure include:
- Corrosion caused by moisture and road salt
- Stone and debris impact damage
- Accident or kerb strike damage
- Age-related deterioration
- Metal fatigue
- Improper handling during brake servicing
- Long-term environmental exposure
Over time, corrosion can weaken the plate, causing distortion, cracking or complete failure.
When Should a Brake Disc Backing Plate Be Replaced?
Brake backing plates should be inspected whenever brake discs or wheel bearings are serviced.
Common signs replacement is required include:
- Visible rust or corrosion
- Cracked or damaged plate edges
- Bent or distorted backing plates
- Contact between the plate and brake disc
- Excessive brake dust contamination
- Missing sections caused by corrosion
- Restoration or refurbishment projects
- Suspension rebuild work
If the backing plate begins rubbing against the brake disc, it should be replaced immediately to prevent noise and potential damage.
Why Replacement Matters
A damaged brake backing plate can compromise protection of the braking system and detract from the quality of a restoration.
Benefits of replacement include:
- Improved brake component protection
- Reduced contamination from road debris
- Correct brake cooling airflow management
- Improved reliability
- Restoration of factory appearance
- Prevention of brake disc contact issues
- Enhanced long-term durability
- Ideal for restoration and maintenance projects
For classic Porsche models, replacing worn backing plates helps preserve both function and originality.

- Porsche 356C 1963-65
The OE Match Rear Brake Disc Cover Plate is a premium-quality replacement brake and suspension component designed to protect the rear brake disc and braking assembly on compatible Porsche models. Manufactured to OE specifications for fit, strength and durability, this precision-engineered backing plate acts as a protective shield, helping to prevent dirt, water, stones and road debris from reaching the brake disc while supporting efficient brake cooling and prolonging component life.
Sold Each.
x2 Required Per Car.
Fits:
- Porsche 356C 1963-65
Manufactured from high-quality automotive-grade pressed steel with a durable corrosion-resistant coating, the cover plate is engineered to withstand continual exposure to moisture, road salt, brake dust and extreme operating temperatures. Precision-formed to match the original Porsche dimensions and mounting points, it provides direct OE-style fitment, making it the ideal replacement during brake overhauls, suspension repairs or restoration projects.
What This Product Does:
- Protects the rear brake disc from road debris and contaminants.
- Helps shield the braking system from water, dirt and stones.
- Supports efficient airflow around the brake assembly.
- Reduces the risk of premature brake component wear.
- Maintains correct positioning behind the brake disc.
- Helps protect the parking brake components where fitted.
- Restores factory brake protection.
- Forms an essential part of the rear braking system.
Symptoms Of Wear Or Failure:
- Corroded or rusted backing plate.
- Bent or distorted cover plate contacting the brake disc.
- Scraping or rubbing noises while driving.
- Missing or damaged brake disc shield.
- Increased exposure of brake components to dirt and debris.
- Loose or broken mounting points.
- Visible corrosion or deterioration.
- Excessive brake dust accumulation around protected components.
- Reduced protection for parking brake assemblies where applicable.
- MOT or inspection advisory due to damaged brake shield.
Why Replacement Matters:
- The rear brake disc cover plate is constantly exposed to harsh road conditions, including water, mud, salt, brake dust and stone impacts. Over time, corrosion and physical damage can weaken the plate, causing it to rust through, distort or detach from its mounting points.
- A damaged cover plate can rub against the brake disc, creating unwanted noise and potentially affecting braking performance. Without adequate protection, brake components become more susceptible to contamination, corrosion and premature wear, reducing their service life.
- Replacing a worn or damaged cover plate with the OE Match Rear Brake Disc Cover Plate restores factory protection for the rear braking system. Manufactured to OE standards using premium corrosion-resistant materials, it provides factory-style fitment, exceptional durability and dependable long-term reliability, helping maintain braking performance, component longevity and the safety expected from your Porsche.
