I’m having issues with the rear caliper of my 2007 Shimano LX caliper. One of the piston’s does not move outward to the same extent as the other. I’ve bled it, and pushed it out as far as it’ll go to lube it with mineral oil but no improvement. It was sticking and took alot of pressure to get it back to its original position (the other piston moved back freely and smoothly). I think this has been going on for a while, i’m going through brake pads quite quickly as one side is wearing alot quicker than the other – pressumably as a result of pressure being applied unevenly.
Any soltions or new caliper time?
Any help gratefully received.
