'86 4KQ emergency brake repeatedly freezing

[sabutin@mindspring.com]

   Hi all...

   I've got a samll question about my '86 4KQ. The emergency brake has
repeatedly frozen since it got cold here in NY, something that NEVER
happened w/my previous Audi, an '83 4K. It first froze engaged; after it
thawed I decided not to use it on moist nights when the temperature supposed
to drop a great deal, on the advice of my trusty Audi mechanic. Now it's
frozen UNengaged, so I can't use it at all, as long as it stays cold. Is
there a quick fix? Something particularly wrong w/mine? Are the '86s
different from the '83s? I don't mind chocking the wheels, but it IS a pain
in the ass, and since I bought it primarily because of its winter
abilities...any suggestions?
   
   Thanks,
   Sabutin
