so i just bought an 01 cobra the other day and from the day i bought it there has been a noise coming from the driver side wheel. its like a chirping or squeeking noise every time the wheels rotates so it gets worse as i go faster. it does not however make a noise if the brake is being applied even the slightest bit. so i'm thinking there is something on the disc that comes around and kits the brake pad everytime or something like that. any ideas on what could be wrong and what to do about it?
