I have an old pair of Shimano XTs pre servowave 2pots
the calipers weap oil not at an alarming rate but enough to contaminate the pads when left sitting over night. Brake still feels solid a year later but the howling is doing my- and those i ride withs nut in.
pistons are in good condition – i boiled them coming down ben nevis north face path a while back with 160mm rotors and they have done it since so i reckon ive fudged the seals –
anyone tried taking them apart and seeing if this seal is just a square oring & perhaps a common part bought in to make the brakes up( i cant see them making it specially)
just wondering if anyones done this before i dismantle them for no reason.
I cant see any issue with doing the work as the pistons are easy enough to get out – ive had them out to clean them up and check them – its not like hope where you really need to take the bore back out
