Developed as part of the specialist Performance Range, this
premium brake caliper rebuild kit combines replacement pistons with upgraded
high-temperature sealing components, delivering superior durability and braking
reliability under demanding driving conditions.
Kit Contents
• 2 x 36mm Pistons
• 2 x 36mm Performance Dust Seals
• 2 x 36mm Performance Piston Seals
• 2 x 40mm Pistons
• 2 x 40mm Performance Dust Seals
• 2 x 40mm Performance Piston Seals
• 2 x Bleed Nipples
• 2 x Bleed Nipple Dust Covers
Designed for fast road driving, spirited use, track-day events and performance-focused Porsche ownership, this kit helps maintain optimum caliper operation when exposed 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 specifically developed to withstand the extreme temperatures generated by modern high-performance braking systems.
Performance Range Key Advantages
High-Temperature Silicone Dust Seals
Performance Range kits utilise premium silicone dust seals instead of traditional OEM-style EPDM rubber dust boots.
Benefits include:
• Exceptional resistance to elevated brake temperatures
• Improved flexibility during repeated thermal cycles
• Increased durability under demanding braking conditions
• Reduced risk of heat-related seal degradation
• Enhanced protection against dirt, moisture and contamination
Enhanced Thermal-Resistant Piston Seals
The piston seals are manufactured using an upgraded EPDM compound developed specifically for high-performance braking applications.
Advantages include:
• Increased resistance to high operating temperatures
• Improved sealing performance under heavy braking loads
• Enhanced long-term reliability
• Greater resistance to thermal fatigue
• Consistent caliper performance during demanding use
Why Choose the Performance Range?
Performance driving places significantly greater demands on brake components than everyday road use. During repeated heavy braking, temperatures can rise dramatically, accelerating wear on conventional seals and reducing long-term reliability.
The upgraded materials used throughout the Performance Range help maintain brake caliper efficiency and sealing integrity when exposed to:
• Repeated heavy braking cycles
• High operating temperatures
• Fast road driving
• Track-day environments
• Motorsport-inspired applications
• Aggressive driving conditions
This makes the kit an ideal preventative maintenance upgrade for Porsche owners seeking enhanced brake system durability and performance.
Ideal Applications
Perfect for:
• Porsche 964
• Porsche 986 Boxster
• Porsche 987 Boxster
• Porsche 987 Cayman
• Fast road driving
• Track-day use
• Motorsport-inspired builds
• Brake caliper refurbishment projects
• 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.
