The front brake caliper repair kit helps restore proper caliper function by renewing components that can wear, harden, split, or leak over time. Correct caliper sealing is essential for maintaining brake fluid pressure, preventing leaks, and ensuring consistent braking response.
Functions
• Repairs and services the front Big Red brake caliper
• Supports correct hydraulic brake pressure
• Helps prevent brake fluid leaks from the caliper
• Restores reliable caliper sealing performance
• Suitable for caliper rebuilds and brake system restoration
• Replaces worn, hardened, split, leaking, or damaged sealing components
• OE Match replacement kit for Porsche 964 and 993 brake caliper service.
Why Replace This Kit?
Brake caliper seals and related service parts are exposed to heat, brake fluid, pressure, road dirt, moisture, and repeated braking cycles. Over time, these components can harden, crack, swell, split, or lose sealing performance. A worn caliper may cause brake fluid leaks, sticking pistons, uneven braking, soft pedal feel, brake drag, or reduced braking efficiency. Rebuilding the caliper with a repair kit helps restore safe and dependable brake operation.
When to Replace This Kit
• The front caliper is leaking brake fluid
• The brake caliper is being rebuilt or refurbished
• Caliper pistons are sticking or not retracting correctly
• Brake drag, uneven braking, or poor pedal feel is present
• Seals are cracked, swollen, hardened, or damaged
• Big Red calipers are being restored or powder coated
• Preventative brake overhaul is being carried out.
Where it fits on the car

Information
Brake Disc Mounting Screws. M6 x 16. (for vehicles with 5mm spacers/Factory option XRP)
2 x Brake disc screws are required per disc/5mm spacer.
Brake disc retaining screw is an extended length fixing screw designed specifically for Porsche vehicles fitted with factory 5mm wheel spacers. It secures the brake disc (rotor) to the wheel hub, ensuring correct disc positioning during wheel installation and brake servicing. On vehicles equipped with factory spacers, standard-length disc screws are too short to achieve proper thread engagement. This longer version compensates for the additional spacer thickness, allowing the brake disc to seat correctly against the hub and remain accurately aligned until the wheel bolts are installed. Manufactured to Porsche factory dimensions and thread specification, this screw provides correct fitment, corrosion resistance, and reliable retention during service and assembly. It is a critical but often overlooked component when working on cars with OEM wheel spacers.
Fits:
Porsche 996
Porsche 997.1
Porsche 997.2
Porsche 991.1
Porsche 991.2
Porsche Boxster 986

Why Replacement Matters:
Using a standard-length brake disc screw on a spacer-equipped hub can result in insufficient thread engagement, leading to poor disc retention or stripped threads. Replacing missing or incorrect screws with the proper extended version ensures correct assembly, avoids hub damage, and maintains factory-correct brake installation.
