any sure fire fixes? Tried bleeding and rebleeding, cleaning with water, isoprop, and lubing with red rubber grease, mineral oil, silicon spray, float fluid, 15wt suspension oil, 5w30 fully synth motor oil (not all at once 🙂 ). Whatever I do, one piston is always much more active than the other.
These are shimano XT calipers with citroen fluid. Does the shimano fluid lubricate better?
Tempted to chuck the bastards in the bin and pick up some Deores.
