Sticky Brakes

[Greg Johnson <gregsj@iea.com>]

Fellow Audians;

Once you own a quattro, it's hard to go back to two wheel drive.  When
it was time to buy a vehicle to haul the family (and all of our junk) I
insisted on a "quattro" and we ended up buying a AWD Chevy Astrovan.  We

were on trip this weekend and my wife sent me out for a few groceries.
At about 40 mph, I thought I had a flat tire.  When I stopped to look,
the tires were fine, but the left rear drum brake was smoking.
Apparently, the parking brake did not release all the way.  I tried the
brake release again, but the left rear remained on.  I slowly "limped"
into town and a mechanic agreed to have a look.  As it turned out, he
had to wait until the next morning before anything would come loose.  He

couldn't find anything wrong this morning and suggested that I probably
forgot to release the brake.  I told him I considered that, but why
would it just be the left rear brake and not the left & right.  Anyone
have any ideas?  Anything I should do?  Replace the drum?  the Shoes?
Please reply off list.  TIA for your help.
