Hello all, I'm sorry for not following the rules of the forum but right now I'm desperate so help would be much appreciated. I changed both front pads for a friend and unwittingly took off the caliper just to replace the pads. Yes i know, a foolish thing to do. So after I took of the calipers, replaced the pads, put everything back together, lined everything up, and put more brake fluid and bled the brakes. Everything seemed ok but two weeks later, the brake fluid leaks out the lining of the caliper. I read that I might have messed up the o ring. But I'm not sure. I would like help as soon as possible so I can remedy this problem. If possible id like to change the o rings but not buy new calipers. Basiclly I want to fix the problem without the problem rresurfacing again. Any tips and step by step procedures would greatly be appreciated.
