Diagram Ref No 3, 4, 5 and 6
What it does:
• Shields the rear brake discs from dirt, debris, and road spray
• Helps maintain efficient cooling and protects the rotor surfaces
Over time, the original cover plates can corrode, warpage, or suffer from broken fasteners. A replacement kit restores protection, preserves brake component integrity, and maintains that authentic appearance.

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.
Why Replace or Upgrade Your Porsche Brake Disc Cover Plates?
Replacing damaged or corroded cover plates restores essential protection to your braking system and maintains performance consistency. Design911’s high-quality replacements are designed for longevity, heat resistance, and accurate fitment across Porsche models.
