09 Design BBK 4-Pot Caliper Service Kit – Per Caliper – Ford Fiesta Mk8/8.5
Restore sharp, reliable braking from your 09 Design 4-piston calipers with this service kit. Heat, dust and old brake fluid can harden seals over time. Refreshing them helps stop fluid leaks, improves pedal feel and keeps braking consistent on road or track.
This kit is built for 09 Design 4-pot calipers used in the Fiesta Mk8/8.5 big brake kit. The seals use high temperature materials to handle hard use and repeated heat cycles.
Fitment
Designed for 09 Design BBK on Ford Fiesta Mk8/8.5. Compatible with ZERONINE Big Brake Kit code FBR017AA. Not for 909 Motorsport kits. Use our vehicle lookup to confirm fitment or see the Vehicle Fitment tab.
What you get
- 4 x piston seals matched to the caliper piston sizes
- 4 x dust seals matched to the caliper piston sizes
Each kit services one caliper. Order two kits to overhaul a full front axle.
Why it matters
Fresh seals help the pistons retract smoothly and keep dirt and moisture out. This reduces brake fade, keeps braking force consistent and extends caliper life.
Installation and safety
Cleanliness is critical. Use fresh brake fluid and bleed the system after fitting. Professional installation is recommended if you are unsure. Inspect braking components regularly, especially after track use.
