I was having some issues (still am) with the pads not releasing all the way back off to original position. I unbolted the caliper from the frame to clean it. Although it got a little better it still does not fully release. Now I notice some definite play in the caliper. Where the right (rear) pad is housed. That whole assembly has well over 1/16" of play. All bolts are fully secured. What did I do wrong? Thanks.
