When I got my 54 3600 it has set for 10 year and everything was stuck. I drug the truck to get the brake shoes loose. The drums were also stuck, so soaked the nut and drum with WD40 for a couple of weeks. Put a wheel puller on the drum and wacked it with a 2 pound sledge and they pupped loose. As a side issue the 54 year old drums were junk and needed be replaced.
