09 Design BBK 6-Pot Caliper Service Kit – Per Caliper
Restore consistent braking and extend caliper life with this 09 Design service kit for 6-piston calipers. Heat, dust and old brake fluid can harden seals and reduce performance. Fresh seals help stop leaks, improve pedal feel and keep the caliper moving smoothly under load.
The kit replaces all internal piston seals and outer dust boots with high temperature, brake fluid resistant parts, made to precise tolerances for a direct fit on 09 Design 6-pot calipers. Ideal for fast road and track-focused cars where calipers see sustained heat.
What you get
- X6 piston seals matched to the correct piston sizes
- X6 dust seals matched to the correct piston sizes
One kit services one caliper. For both front calipers, order two kits.
Fitment
Direct fit for 09 Design 6-pot calipers used in the following 09 Design Big Brake Kits: Focus ST Mk4/Mk4.5 (FBR019AA) and Puma ST 1.5 (FBR023AA). Not compatible with 909 Motorsport brake kits.
Use our vehicle lookup to confirm fitment, or see the Vehicle Fitment tab for full details.
Why service your calipers
New seals help maintain hydraulic pressure, reduce brake fade, and keep pedal feel firm. Dust boots protect pistons from debris, reducing sticking and uneven pad wear. Regular servicing supports reliable stopping power.
Notes
We recommend a clean workspace, quality brake fluid, and careful inspection of pistons and bores. If any hard parts are damaged or corroded, replace them before reassembly. Bed brakes in after service and check for leaks.
