The OE Match Spring Plate Rear Brake Caliper Upper is a precision-engineered brake hardware component designed to secure and stabilise the brake pads within the rear brake caliper assembly. Manufactured to OE specifications for fit, tension and durability, this upper spring plate plays an important role in maintaining correct brake pad positioning and ensuring smooth, quiet brake operation.
Sold Each.
x2 Required Per Car.
Fits:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1978-1989 3.3L Turbo (930)
Diagram Ref No 12
Constructed from high-strength spring steel with a corrosion-resistant finish, the spring plate is designed to withstand the demanding conditions of the braking system, including high temperatures, vibration and repeated braking cycles. It helps maintain consistent pressure on the brake pads, reducing unwanted movement and contributing to reliable braking performance.
What This Product Does:
- Secures and stabilises brake pads within the rear brake caliper.
- Maintains correct brake pad positioning during operation.
- Reduces brake pad vibration and movement.
- Helps minimise brake noise and rattling.
- Supports even brake pad contact with the brake disc.
- Contributes to consistent braking performance.
- Assists in reducing uneven brake pad wear.
- Forms an essential part of the rear brake hardware assembly.
Symptoms Of Wear Or Failure:
- Rattling noises from the rear brakes.
- Excessive brake pad movement within the caliper.
- Brake squeal or vibration during braking.
- Uneven brake pad wear.
- Reduced brake pad stability.
- Corrosion or rust on the spring plate.
- Loss of spring tension.
- Distorted or damaged retaining hardware.
- Premature wear of brake components.
- Poor brake feel under certain driving conditions.
Why Replacement Matters:
- Brake spring plates are subjected to continuous heat cycles, vibration, moisture, road contaminants and repeated mechanical stress. Over time, the spring material can weaken, lose tension or become corroded, reducing its ability to hold the brake pads securely in place.
- A worn or damaged spring plate can allow excessive brake pad movement, leading to unwanted noise, uneven wear and reduced braking refinement. If left unresolved, loose brake hardware may accelerate wear of the pads, caliper components and brake discs.
- Replacing a worn spring plate restores proper brake pad retention and helps maintain smooth, quiet and reliable braking performance. An OE Match replacement provides factory-style fitment, correct spring tension and long-lasting durability, ensuring the braking system continues to perform safely and effectively while maintaining the driving standards expected from your Porsche.

Genuine Porsche disc brake pad hardware kit contains all necessary retaining pins and spring clips used to mount and secure the front brake pads in the caliper on classic Porsche 911 models built between 1984 and 1989.
One brake pad pin kit is for both front calipers.

Fits:
Porsche 911 3.2L 1984 - 1989
Diagram ref no 18.
The hardware kit includes precision-made retaining pins and spring clips that secure the brake pads inside the front caliper carrier. These components ensure the pads remain correctly positioned, slide freely as intended, and apply even pressure when braking - helping the pads wear evenly and perform reliably.
Function: Brake pad hardware is essential for maintaining proper brake function. The retaining pins and clips guide the pads during engagement and release, help prevent noise and vibration, and ensure consistent braking performance. Genuine Porsche hardware resists corrosion and wear, preserving smooth pad movement and long service life.
Proper brake pad hardware ensures correct pad retention and movement - critical for safe braking performance. Worn, corroded, bent, or missing pins and clips can lead to: Uneven pad wear Brake noise such as squeal or rattle Inconsistent braking force Reduced pad life Installing a Genuine Porsche hardware kit restores factory-recommended guidance and clamping of the pads, supporting reliable brake modulation and quiet operation.
When to replace:
Replace your brake pad hardware kit if:
• The pads bind, stick, or don’t slide smoothly
• Pins or clips are rusted, bent, or damaged
• You’re replacing brake pads or rotors
• You’re servicing the front calipers and want complete factory renewal
