Crooked Piston in Shimano R-R505 Disc Brakes
#1
My original set of rear pads prematurely expired due to crooked wear on the outside pad. Upon closer inspection I see the piston extends at an angle, or crooked. This is not how the front brake extends (same model). Anyone know if opening the caliper to address this is possible? Thanks
