anotherfive Posted January 24, 2021 Report Share Posted January 24, 2021 A general question really for many bike variants. Sometimes the pots in the caliper don't move outwards at the same rate. Obviously its either muck or dry seals etc that's causing friction.I can work them free using little clamps on opposing pots but once done what oil if any would you try to use on the seal area?

Cee-B Posted January 24, 2021 Report Share Posted January 24, 2021 Either simply use brake fluid or use any proprietary brake caliper grease, there are plenty of them on the market. Quote Link to comment Share on other sites More sharing options...
Matt185 Posted January 24, 2021 Report Share Posted January 24, 2021 Agree - Give the caliper assembly a good clean first and then with care, remove each piston and give them a thorough clean with brake cleaner.Then ideally using the same brake fluid as in the rest of the system - work a little fluid into the seal and reinstall each piston.Give the caliper a good clean up afterwards.
