Rear Brake Caliper Piston Dust Cap and Seal Kit. Porsche 964 Carrera 2 1990-91 ❭ 964069244
- Porsche 964 (911) C2 1989-93
Rear Brake Caliper Piston Dust Cover & Seal Kit
1 kit per caliper - 2 required per car
High-quality rear brake caliper piston dust cover and seal
kit designed specifically for Porsche 964 Carrera 2 models (1990–1991) equipped
with 2 piston rear calipers. This kit provides all essential sealing components
required to restore braking performance and maintain hydraulic integrity.
Fits:
- Porsche 964 (911) C2 1989-93
Kit includes
2 x 44mm piston dust caps
2 x 44mm piston seals
2 x bleed nipple covers
Manufactured to OEM standards, these components prevent brake fluid leaks, protect against dirt and moisture ingress, and ensure smooth piston operation. Ideal for maintenance, repair, or rear brake caliper rebuilds on classic air-cooled Porsche models.
Key Features
• Rear brake caliper dust cap and seal kit
• Suitable for Porsche 964 Carrera 2 (1990–1991)
• Maintains hydraulic sealing and pressure
• Protects against contamination and corrosion
• OEM-quality materials for durability and reliability
Function and Purpose
This kit is essential for maintaining rear brake caliper performance.
It helps to:
• Seal brake fluid within the caliper
• Protect pistons from dirt, debris, and moisture
• Maintain consistent braking pressure
• Ensure smooth piston movement
• Prevent corrosion and internal wear
Why Replace Rear Caliper Seals
Brake seals degrade over time due to heat and exposure.
Common issues include:
• Brake fluid leaks
• Reduced braking efficiency
• Sticking or seized pistons
• Uneven brake wear
• Corrosion caused by moisture ingress
Replacing seals restores braking performance, safety, and reliability.

DOT 4
Having an extremely high boiling point and lower viscosity than required, it meets and greatly exceeds regulatory standards. Also suitable for vehicles with ABS.
Vapour Lock formation
This sort of habit leaves room for the Vapour Lock, the formation of vapour bubbles due to boiling of the brake fluid that replace the normal fluid and are compressed, thereby sending the brake pedal to its fill stoke (spongy pedal). The origin is incident in the porosity of the tubes that make up the braking circuit, which in time draw moisture into the fluid, drastically reducing the boiling point. The result is a reduced braking efficiency.
Brembo Premium Brake Fluid
Brembo Premium brake fluids have a higher boiling point that exceeds the standard, thus offering superior resistance to the Vapour Lock and ensuring braking efficiency even at low temperatures. With high anti-corrosion properties and resistance to oxidation, Brembo brake fluid also allows for long-term unaltered chemical/physical characteristics of the fluid in operating circuit; therefore, preserving its integrity.
