Another question, I have a front brake that keeps getting hot so I pulled the wheel and caliper to have a look and one of the two spring loaded pushers that keeps the slack out of between the brake pad and the disk is pushed out tight not letting the brake pad release. The pusher is "frozen" out, the other one you can push in with your finger. I have put a wrench on the "pusher" but am afraid of putting to much stress on it. Any ideas??? Thanks, Luke
