Brake Disc Cover Plate, Front
Restore an important protective component of your classic
Porsche braking system with this OE Match Front Brake Disc Cover Plate. The cover plate sits behind the front brake disc and
helps protect the braking assembly from road dirt, stones, water and other
debris.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)

On early Porsche 911 models, the original cover plates can suffer significant deterioration after decades of exposure to moisture, road contamination and repeated heating and cooling cycles. Replacing a damaged or heavily corroded plate is particularly worthwhile when carrying out a front brake overhaul or restoration.
What Does a Brake Disc Cover Plate Do?
The front brake disc cover plate, also commonly referred to as a brake backing plate or dust shield, sits behind the brake disc and provides a protective barrier around the braking assembly.
Its functions include:
- Helping shield braking components from road debris
- Reducing exposure to dirt and contamination
- Protecting the rear face of the brake disc area
- Maintaining the correct factory-style brake assembly
- Providing a complete finish during restoration
Why Do Brake Disc Cover Plates Fail?
Brake disc cover plates operate in a harsh environment where they are continuously exposed to moisture, road grime, heat and temperature changes.
Age-related corrosion is particularly common on classic Porsche 911 models. The plate can eventually weaken, crack or lose material around its edges and mounting points.
Damage may also occur during previous brake, wheel bearing, hub or suspension work. A distorted plate can potentially contact the rotating brake disc and create unwanted scraping or rubbing noises.
When Should They Be Replaced?
Replacement should be considered when:
- The original plate is heavily corroded
- Sections have rusted away
- The plate is cracked or distorted
- Mounting points are damaged
- The plate is rubbing against the brake disc
- Restoring or rebuilding the front braking system
- Carrying out a comprehensive classic
- Porsche restoration
Replacing deteriorated cover plates while the front brake assembly is already dismantled can also help avoid additional labour later.
Porsche 911 1965-68 Front Brake Disc Cover Plates
Maintaining the braking system of an early Porsche 911 involves more than replacing brake discs and pads. Protective components such as the front brake disc cover plate can deteriorate considerably over time and should be inspected whenever the front braking, hub or wheel bearing assembly is dismantled.
For owners searching for a Porsche 911 1965-68 front brake backing plate, brake dust shield or brake disc protector, this OE Match replacement provides a practical solution for restoring an ageing braking system.
Replacing corroded brake cover plates alongside other front brake components helps return the assembly to a clean, complete and properly protected condition, making them particularly suitable for restoration projects and preventative maintenance.
Benefits of OE Match Front Brake Disc Cover Plates
- Direct replacement for ageing original components
- Helps protect brake components from contamination
- Suitable for Porsche 911 1965-68 restoration projects
- Ideal during front brake refurbishment
- Useful when replacing discs, bearings or associated brake components
- Helps maintain the original brake assembly configuration

What Does a Brake Disc Cover Plate Do?
The brake disc cover plate, sometimes referred to as a brake backing plate, dust shield or brake disc protector, sits behind the brake disc and provides an additional protective barrier around the braking assembly.
Its functions include:
- Helping protect braking components from road debris
- Reducing exposure to dirt and contamination
- Providing protection around the rear brake disc
- Helping maintain the original brake assembly configuration
Why Do Brake Disc Cover Plates Fail?
Brake cover plates are continuously exposed to heat, water,
road salt and debris.
Over time this can cause corrosion, cracking or
deterioration, particularly on older vehicles or cars frequently driven in wet
conditions.
Damage can also occur during brake, wheel bearing or suspension work if an ageing cover plate is accidentally bent or disturbed.
When Should They Be Replaced?
Replacement should be considered if the original plate is:
- Heavily corroded
- Cracked or damaged
- Loose or distorted
- Rubbing against the brake disc
- Missing sections due to corrosion
- Being removed during a comprehensive brake restoration
Replacing deteriorated plates while the rear braking system is dismantled can also save additional labour later.
Rear brake disc cover plates are an often-overlooked component when maintaining or restoring a Porsche braking system. While brake discs and pads are regular service items, the protective plates behind them can gradually deteriorate after years of exposure to heat, moisture and road contamination.
Replacing damaged Porsche rear brake backing plates helps restore the braking assembly to a complete and properly protected condition. These OE Match cast brake disc cover plates provide a suitable replacement for Porsche owners carrying out brake servicing, restoration or rear suspension refurbishment.

Porsche Brake Disc Cover Plates | Design911 High-Quality Replacement Parts for Protection, Cooling & Longevity
Brake disc cover plates, also known as backing plates or dust shields, are essential components that protect your Porsche’s brake discs and calipers from dirt, debris, and excess heat. Positioned behind the brake disc, they help maintain consistent braking performance by shielding the braking system from contaminants and improving cooling airflow. Whether used for restoration or maintenance, replacing worn cover plates helps preserve braking efficiency and prolong component lifespan.
At Design911, we offer a complete range of brake disc cover plates, precision-engineered for perfect fitment and durability. Manufactured from corrosion-resistant materials and designed to handle high thermal loads, our cover plates ensure long-term reliability and protection under both road and performance driving conditions. Ideal for service, restoration, or upgrade projects, these components maintain your Porsche’s stopping power and integrity.
What Do Brake Disc Cover Plates Do?
Brake disc cover plates perform a crucial protective and thermal management role within your Porsche’s braking system.
Core Functions:
• Shield brake discs and calipers from road debris, water, and dust.
• Assist with heat dissipation during braking.
• Reduce corrosion by preventing contaminant buildup.
• Maintain consistent braking efficiency and performance.
• Contribute to proper airflow for cooling under braking load.
With effective cover plates, your Porsche’s braking components stay cleaner, cooler, and more reliable for longer periods.
Why Do Brake Disc Cover Plates Fail or Degrade?
Due to their position near the road surface and braking components, cover plates are constantly exposed to moisture, dirt, and extreme temperature changes.
Common Causes of Failure Include:
• Corrosion or rust caused by road salt and moisture.
• Physical damage from road debris or gravel.
• Cracking or warping from heat and vibration.
• Bending due to improper installation or impact.
• General wear over time from environmental exposure.
When cover plates deteriorate, they lose their protective function — allowing dirt and moisture to affect the braking system, which can lead to premature wear or reduced performance.
