• 2 x Bleed Nipple Dust Covers
Whether used for fast road driving, spirited mountain routes, track days, or motorsport-inspired applications, this kit helps maintain optimal brake caliper performance and reliability under demanding conditions.
Unlike conventional seal kits, the Performance Range incorporates upgraded silicone dust seals and enhanced thermal-resistant piston seals specifically developed to provide superior durability and heat resistance during repeated heavy braking cycles.
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 extreme operating temperatures
• Improved sealing performance under heavy braking loads
• Enhanced long-term reliability
• Greater resistance to thermal fatigue
• Consistent caliper operation during demanding use
Why Choose the Performance Range?
The Porsche 991 Turbo and GT2 RS equipped with PCCB braking systems are capable of generating immense braking forces and temperatures. During fast road driving and track use, brake components are subjected to extreme thermal loads that can accelerate wear on standard caliper seals.
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
• High-performance driving conditions
This makes the kit an ideal preventative maintenance upgrade for Porsche owners seeking maximum brake system durability and reliability.
Ideal Applications
Perfect for:
• Porsche 991 Turbo with PCCB
• Porsche 991 GT2 RS with PCCB
• Fast road driving
• Track-day use
• Motorsport-inspired builds
• High-performance brake system maintenance
• Brake caliper refurbishment projects
• Vehicles subjected to repeated heavy braking cycles

OEMatch Caliper Seals |Pistons — Stopping Power, Consistent Control
OEMatch caliper seals and pistons for Porsche models restore hydraulic integrity and consistent brake response. These restoration and repair components are practical alternatives when genuine or OEM parts are unavailable, offering direct-fit replacements engineered to match original-spec dimensions and tolerances. OEMatch maintains extensive cross-references to support model-specific servicing.
Available Types
- Seal kits — piston seals and dust boots
- Replacement pistons — steel and phenolic options
- Rebuild kits including seals, pistons and associated fittings
Understanding OEMatch Caliper Seals |Pistons
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche's original caliper seals and pistons. OE (Original Equipment) refers to parts matching original specifications for the caliper seals and pistons and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM caliper seals and pistons engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Caliper pistons convert hydraulic pressure into pad clamping force while seals retain fluid and exclude contamination. Correct materials, surface finish and seal geometry reduce the risk of corrosion, piston scoring and sticking. Components listed here are chosen to address common Porsche service needs and to support caliper rebuilds across different models.
Benefits Include
- Restores hydraulic integrity to prevent leaks and maintain consistent pedal feel
- Improves caliper response and even pad wear
- Reduces corrosion and fluid-related deterioration
- Supports reliable retraction and balanced braking across wheels
Why Caliper Seals |Pistons Wear and Fail
- Aging and brake fluid degradation that harden or swell seals
- Corrosion and pitting on pistons from moisture ingress
- Heat damage from sustained or aggressive braking
- Contamination or debris causing seal abrasion and piston scoring
The Importance of Replacing with OEMatch Caliper Seals |Pistons
Worn seals and pistons compromise braking performance and can lead to leaks, uneven braking or sticking calipers. Replacing these parts restores consistent system pressure, pedal feel and safety-critical function; selecting components matched to Porsche specifications helps maintain correct clearances and long-term reliability without altering system behaviour.
Advantages
- High-quality materials chosen for corrosion and fluid resistance
- Made to original-spec dimensions and tolerances for Porsche models
- Suitable for restorations, routine servicing and caliper rebuilds
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and replace fasteners where specified. If you lack the correct tools or are unsure about hidden sensors or required recalibration, seek professional installation.
