Please check piston diameters before ordering
The Performance Range has been engineered as an advanced brake system upgrade, using enhanced materials designed to deliver superior durability, improved thermal resistance, and long-term sealing performance under demanding driving conditions.
Kit contains
2 x 36mm Performance Dust Seals
2 x 40mm Performance Dust Seals
6 x 36mm Performance Piston Seals
6 x 40mm Performance Piston Seals
2 x Bleed Nipple Dust Covers
Unlike standard OEM-style rebuild kits, the Performance Range incorporates upgraded high-temperature materials specifically selected to withstand repeated heavy braking cycles and extreme thermal loads experienced during spirited driving and motorsport-inspired use.
Ideal for Porsche owners seeking improved brake caliper reliability and durability for road, fast road, and track applications.
Key Features
• Performance brake caliper seal kit
• Designed for high-performance Porsche braking systems
• Engineered for fast road and track use
• Improved thermal resistance over OEM-style kits
• Enhanced durability during repeated heavy braking
• Helps maintain brake caliper sealing integrity
• Suitable for motorsport-inspired Porsche builds
Performance Range – Designed for Demanding Driving Conditions
The Performance Range has been specifically developed as a brake system upgrade for applications exposed to higher thermal loads and intensive braking use.
Perfect for:
• Fast road driving
• Spirited performance use
• Track-day applications
• Motorsport-inspired Porsche builds
• Vehicles subjected to repeated heavy braking cycles
The upgraded materials help maintain consistent sealing performance and durability under conditions where standard OEM-style components may deteriorate more quickly.
High-Temperature Silicone Dust Boots
Performance kits use silicone piston dust boots instead of traditional OEM-style EPDM rubber dust seals.
Silicone offers:
• Improved resistance to elevated brake temperatures
• Increased flexibility during heat cycles
• Better long-term durability under demanding use
• Enhanced protection against contamination
• Reduced risk of heat-related deterioration
Ideal for performance braking systems exposed to sustained high temperatures.
Enhanced Thermal-Resistant Piston Seals
The piston seals are manufactured using an upgraded EPDM compound specifically developed for improved thermal resistance and reliability during aggressive driving conditions.
Advantages include:
• Greater resistance to heat-related wear
• Improved hydraulic sealing performance
• Enhanced durability under repeated braking loads
• Long-term reliability for performance applications
• Better protection for brake caliper internals
Why Choose the Performance Range?
The upgraded materials used throughout the Performance Range help improve brake caliper reliability when exposed to extreme heat and repeated high-load braking.
This makes the kit particularly suitable for:
• Porsche GT and RS models
• Fast road performance builds
• Track-day vehicles
• Upgraded braking systems
• Enthusiasts seeking motorsport-level durability

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.
