[s-cars] Faint Thump Noise!

[Fred Munro]

Hi Abhi;

The pad marks will make a thumping noise when you apply the brakes. It will
go away when the marks wear off.

Lee,

I do not feel it in the steering wheel nor the brake pedal. There is
no clicking nor is there any pulsing of the brakes. This *thumping*
most definitely feels like its emanating from the rear and is always
present when driving around town or freeway.

The brakes themselves are Zimmerman rotors and Mintex pads, with
approx 2k miles on them. The car had been parked over a lengthy time
with it's parking brake set, leaving pad marks on the rear rotors.
Could it be the rear calipers sticking?
