I was recently riding and the pads on my rear brake (el camino) began to have a lot of play and sort of flop around in the caliper. I tried taking them out and putting them back in, but am still having the same problem. The little metal clip/spring clips into the little post on the piston, but the brakes pads still seem to have quite a bit of play. the springs do not look bent at all. can anyone help me? it would be greatly appreciated. THANKS
