I have this sound coming from my brakes, It just started a few days ago and it's bugging me like hell. When I'm driving it's a mettalic sound almost like when a brake pad is worn down all the way and metal is rubbing against the rotor. Only thing is that the rotors are a few months old and so are the hawk brake pads on it. I just checked the pads and they are nice and thick so they haven't worn down. It seems to get a little louder when I press on the brakes, but I'm not sure what it could be. If anybody has had this problem or can give me some ideas, let me know. Thanks
