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)  

Diagram ref no 9

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

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.

The mounting plate plays a key role in the brake system’s mechanical integrity, helping anchor the caliper in the proper position relative to the brake rotor and suspension components.

The brake support mounting plate serves several essential functions in the braking system:
•  Provides a stable attachment point for the brake caliper
•  Ensures proper alignment of caliper relative to the brake rotor
•  Distributes braking forces evenly through the suspension and chassis
•  Supports safety-critical brake function under hard stopping

Without a solid mounting plate, the caliper can shift or flex under load, leading to inconsistent braking performance, uneven pad wear, increased noise, and potentially compromised stopping power.

Function:
•  Mounting interface: Secures the brake caliper to the suspension/axle housing
•  Load distribution: Handles braking reaction forces to prevent flex and movement
•  Alignment support: Keeps the caliper centered over the brake rotor
•  Structural reinforcement: Provides rigidity necessary for consistent brake performance.

These support plates are precision-formed to withstand the dynamic loads generated by repeated braking and sudden stops - helping maintain consistent brake feel and vehicle safety.

The brake support mounting plate is a structural component that underpins the entire rear brake assembly’s performance. With age, original plates can:
•  Corrode or rust, weakening structural integrity
•  Bend or distort from impact or over-torque
•  Wear at mounting holes, allowing play or misalignment

A compromised mounting plate can lead to brake vibration, uneven pad wear, inconsistent stopping, and noise. Replacing it with a quality OE Match unit restores proper alignment and rigidity - helping ensure repeatable, reliable brake performance and enhanced safety.

When to replace.  Replace this brake support mounting plate when:
•  There is visible corrosion or rust on the original plate
•  The plate shows bends, dents, or distortions
•  Brake calipers show uneven wear or misalignment
•  You’re performing a rear brake overhaul or suspension service
•  Mounting bolts no longer tighten to torque spec due to elongation or wear
