Designed for fast road driving, spirited use, heavy vehicle applications, and track-focused environments, this kit helps maintain optimal caliper performance 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 heat generated by high-performance braking systems.
Performance Range Key Advantages
High-Temperature Silicone Dust Seals
Performance Range kits feature premium silicone dust seals rather than traditional OEM-style EPDM dust boots.
Benefits include:
• Significantly improved resistance to extreme brake
temperatures
• Enhanced flexibility during thermal cycling
• Improved durability during repeated heavy braking
• Reduced risk of heat-related seal deterioration
• Better protection against moisture, dirt and contamination
Enhanced Thermal-Resistant Piston Seals
The piston seals are manufactured using an upgraded high-performance EPDM compound specifically engineered for increased thermal resistance and long-term durability.
Advantages include:
• Improved sealing performance at elevated temperatures
• Enhanced resistance to brake heat
• Increased long-term reliability
• Reduced seal degradation under demanding use
• Consistent caliper performance under extreme conditions
Why Choose the Performance Range?
Large, high-performance Porsche SUVs place significant demands on braking systems, especially during spirited driving, towing, mountain driving, or track-day use.
The upgraded materials used throughout the Performance Range help maintain caliper performance and sealing integrity when exposed to:
• High operating temperatures
• Repeated heavy braking cycles
• Fast road driving
• Track-day environments
• Performance driving conditions
• Heavy vehicle braking loads
This makes the kit an ideal preventative maintenance upgrade for Porsche Cayenne owners seeking enhanced brake system reliability.
Ideal Applications
Perfect for:
• Porsche 955 Cayenne S
• Porsche 955 Cayenne Turbo
• Fast road driving
• Track-day vehicles
• Motorsport-inspired builds
• Heavy-duty road use
• 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.
