hi, i have a problem about the XT caliper, can anyone tell me why the piston always not in centre (i mean 1 side are more movement than the other side) do i need bleeding? thanks

How old is the brake? Which XT brake is it?

Sounds like a sticky piston, in which case they need cleaning. It's not entirely unusual for one to move slightly before the other, though.

The model is Shimano XT M765. How to clean it?
