Just got hold of some Shimano M765 calipers, saved them from the trash, The pistons were sticking, I popped them out and cleaned them, Is it a known problem with those brakes?
Bonus Q: Is it also known that the Shimano M595 brake can leak? My front brake leaks at the bolt that goes into the caliper, it leaks from above the bolt where the hose is.
