Fitment & Compatibility
Confirm the caliper’s exact seal-kit reference rather than selecting any six-piston Superlite pack. Compare the groove and ring profile, and preserve the larger and smaller locations through disassembly. The piston-seal contents should be assessed separately from any dust protection, crossover seals or mechanical hardware needed for the repair.
