hi - new to the site so would appreciate it if someone could help me. I have a 58 GT, and have noticed an intermittent but terrible rattle when driving, that appears to come from the rear brakes. It happens at all speeds, but not always - it is really distracting with the windows down. Brake/driving performance is not imapacted, and it has been back to garage once already - they said the discs were slightly warped and skimmed them, which did the job for a while (about 1K ago). The car has donee 32K overall. Any ideas?? thanks
