A couple weeks ago we bought an '02 Elantra that only has 31,000 kilometers
from a local Hyundai dealer. Sometimes when the brakes are applied, there's
noise that seems to be coming from the rear brakes. Before buying the car, I
noticed that there was noise at low speed even without applying the brakes.
That noise was definitely something rubbing and it occurred once per wheel
revolution.

Before taking delivery, the dealer cleaned the rear drums and the noise was
gone for a few days. Then it started again, but only when the brakes are
applied lightly and the drums are cold. If we apply the brakes again within
a couple minutes, there is no noise.

On Monday, the dealer machined the drums because they were not perfectly
round. The noise was gone until today. What else could cause that
intermittent noise? I don't believe that having the drums cleaned or
machined twice a week is the solution.

Thanks,
