Fitment & Compatibility
Use the piston specified for the installed caliper body and hydraulic seal. Check both dimensions and the piston construction; shared nominal bore size does not confirm the required replacement. The Thermlock assembly combines a stainless heat shield with a coated aluminum shell to reduce heat transfer toward the caliper body and fluid. Use the complete specified design rather than substituting by diameter alone.
