If you adjusted the brake to compensate for pad wear by pulling the arm through it’s ark with certain leavers you could get the caliper to barf out the ball bearings which resulted in total failure
In that case I assume the brake wouldn't work at all? Mine is still working, it's just the piston that seems to slip back at the end of the stroke. Might have to get the LBS to have a look. Thanks!
Based off that I've got the Version 2 caliper. Do you know what the issues were with the version 1?
