38mm Sumitomo Caliper Rebuild Kit

⚠ Quick Note — Dry Installation Required

Silicone dust boots must be assembled dry — avoid any contact with grease or fluids on the dust boots. Install by hand only to avoid damage.

Please double check your piston/bore measurements against this kit before checking out. Our lookup tool is a helpful guide, but it isn't guaranteed for every setup. Measuring first is the best way to make sure it's the right fit.
