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
2 x 36mm Performance Piston Seals
2 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

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

Repair kit designed to rebuild the rear brake calipers of classic Porsche 911 models from the 1969–77. This kit includes all necessary sealing rings, dust boots and associated hardware required to restore proper hydraulic operation and sealing integrity of the “M-type” steel calipers.
Sold per caliper.

"M" type The S calipers are aluminium and the M calipers are steel
• Position: Rear axle brake caliper assembly—used to rebuild one caliper (sold each).
• Applications: Ideal for use when calipers show signs of leakage, piston sticking, seal degradation or during full brake system overhaul/restoration.
Brake caliper seals and boots are crucial for maintaining hydraulic function, preventing fluid leaks and ensuring piston mobility. When seals wear out, you may experience brake drag, uneven pad wear, reduced stopping performance or fluid leakage. Replacing with a correctly specified kit ensures safe, consistent braking under all conditions.
When and why to replace:
• Visible brake fluid leakage around the caliper body or piston boot.
• Caliper pistons sticking or uneven pad wear.
• Brake overhaul where pistons are removed and seals are exposed.
• Restoration of vehicles where the original seal kit has not been replaced in decades.
