I just put a new (not rebuilt) brake master cylinder on my '92 A4 and noticed when I took it for a short spin that the brakes were not fully releasing.
My brakes were VERY hot by the time I got it back home...
Is there a way to get that master cylinder vacuum to loosen up without taking it back off? Is it possible that something else could be causing the lock-up? (I checked the parking brake...)
