I recently painted my calipers with G2. I didn't remove the calipers but rather painted them while they were on the car. After a few days of driving I noticed a rotating rubbing/grinding sound coming from my front driver side wheel while coasting forward to a stop (or slowly moving forward). The sound does not engage while moving backwards or while moving while my foot is on the gas. I originally thought it was a rock or something that got caught between either the shield or even the pad but I can't find a damn thing. I've had the front wheels off twice already and each time the sound goes away but eventually comes back (usually after hitting a bump). Obviously, since I just painted the calipers I'm looking at that as the cause. Only problem is I'm out of ideas as to why. Is it possible that the paint is gumming up or holding the pad against the rotor? It's not a very pleasant sound and I'd rather not have to take it to the dealer if I can correct the problem. Any thoughts?
