For the last few weeks i have noticed a strange noise coming from my brakes i assume. First I was backing out of my garage when i hit the brakes softly and heard a scraping noise. And since then its been fine except for now when i brake at very slow speeds i notice a clank noise like to pieces of metal being hit together, not all the time though. and 90 percent of the times it has also been going in reverse. not a very loud noise very subtle and only can be heard with the windows down. Any ideas i might just be paranoid. I bought the car a month ago and had it certified so i would think eveything would be fine. I just want to make sure its not a big problem\ sounds like the noise is coming from the front all except once when i think it was the rear brakes i have a GT to 2 disc and 2 drum?? any ideas.. Also once it sounded like something was draging but nothing was. so im kind of confused. I appriciate the help thank you.
