MW will rebuild your 81100 calipers if you have a rebuildable core. We will replace the o-rings, pistons, bleed screws, main bolts, and lock washers with new parts and clean the castings. Sold each.

**Note** We can no longer rebuild calipers with the 1/4" bleed screws.

For options, lead time, more specific technical information, and Return Authorizations, please contact one of MW's technicians. Your calipers must be sent to MW for the rebuild, and a Return Authorization must be issued before you send in your parts.
