I recall reading about some specific adjustment that has to be done to get the caliper piston to extend. Recently I had the 3rd member out to fix a leak. Doing so requires removal of the caliper and pads. I thought that I would try adjusting the pistons out slightly for quicker brake response. I recall someone mentioning that the caliper pistons need to be rotated, that they don't just push straight out like you'd expect. I rotated my right side CCW and it extended too much. I had to sand the brake pads to get the caliper to fit over the pads. What did I do wrong?
