New to the forum. Own a '67 MGBGT that I bought already restored. Car has run just fine for the last 1 1/2 yrs (maybe a total of 5000 miles ) but now I have a mysterious noise that appears to be coming from the rear of the car. When you put on the brakes, SOMETIMES, it grones. This with the trans in neutral and the clutch out. The brakes don't grab, the none of the tires drages or leaves any mark on the road. /ubbthreads/images/graemlins/confused.gifAnyone with any ideas?
