I replaced the front brake pads on my 2004 Expedition. Everything went fine but the retention spring on the drivers side caliper is now so close to the wheel that it rubs sometimes. It also seems like it might fall off because it barely catches the caliper. On the passenger side there is about a 1/4 inch of clearance. I don't think I bent the spring when I took it off but maybe that's it. Should I get a new spring or is there something else to check?
