well i did sum quick clean and lube up again on piston, and push it back in again seem to fix it at mo, but dics still running a lil warmer than the other disc, but doesnt seem to be locking on,
[quote=“Chris H, post: 478492”]if the piston is free and pushes back easily i’d be looking at the flexi for internal collapsing.
the pads ALWAYS run on the pads so warped (which is a myth) or not it won’t cause the issue
