Part of the advanced Performance Range, this comprehensive
caliper rebuild kit combines replacement pistons with upgraded high-temperature
sealing components, delivering exceptional durability and reliability under
demanding braking conditions.
Kit Contents
• 2 x 30mm Pistons
• 2 x 30mm Performance Dust Seals
• 2 x 30mm Performance Piston Seals
• 2 x 34mm Pistons
• 2 x 34mm Performance Dust Seals
• 2 x 34mm Performance Piston Seals
• 2 x Bleed Nipple Dust Covers
Designed for enthusiastic road driving, fast road applications, track days, and motorsport-inspired builds, this kit helps maintain optimal caliper performance when subjected to repeated heavy braking and elevated operating temperatures.
Unlike conventional rebuild kits, the Performance Range incorporates upgraded silicone dust seals and enhanced thermal-resistant piston seals that are specifically engineered to withstand the extreme heat generated by high-performance braking systems.
Performance Range Key Advantages
High-Temperature Silicone Dust Seals
Performance Range kits utilise premium silicone dust seals in place of conventional OEM-style EPDM dust boots.
Benefits include:
• Superior resistance to extreme brake temperatures
• Enhanced flexibility during repeated thermal cycling
• Increased durability during aggressive driving
• Reduced risk of heat-related seal degradation
• Improved protection against dirt, moisture, and contamination
Enhanced Thermal-Resistant Piston Seals
The piston seals are manufactured from an upgraded EPDM compound developed specifically for high-performance braking environments.
Advantages include:
• Improved heat resistance
• Enhanced sealing performance
• Increased long-term durability
• Greater resistance to thermal fatigue
• Consistent brake caliper operation under demanding conditions
Why Choose the Performance Range?
High-performance Porsche models such as the 964 Carrera 4, Turbo, and RS place significant demands on brake components, particularly during spirited driving and track use.
The upgraded materials used throughout the Performance Range help maintain caliper integrity and sealing performance when exposed to:
• Repeated heavy braking cycles
• High operating temperatures
• Fast road driving
• Track-day environments
• Motorsport-inspired applications
• Aggressive mountain and touring routes
This makes the kit an ideal preventative maintenance upgrade for Porsche owners seeking enhanced brake system reliability and performance.
Ideal Applications
Perfect for:
• Porsche 964 Carrera 4
• Porsche 964 Turbo
• Porsche 964 RS
• Fast road driving
• Track-day use
• Motorsport-inspired builds
• Performance brake system rebuilds
• Vehicles subjected to repeated heavy braking cycles

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.
