Clunk from passenger side rear when braking?

I recently bought a mint 2003 GT convertible, with auto tranny. Love the car!

I have not taken any of the wheels off yet....no need to, so I have not inspected the brake system closely....the rotors look fantastic and the calipers look as new.

What I notice is a clunk (thud) that seems to be from the passenger rear end, when braking as I am slowing to 10 or so mph.

I am thinking it could need grease on the rear caliper slides????

The car was stored inside a heated parking garage each winter...so it sat for at least half of each year.



Thanks

Good point.

I will pull the wheels and look it over.
