Use a torch and heat the drum around the axle end. Try not to haet the axle as it won't have the effect you are wanting. Most of the time they are tight around the little circle. Now if its the shoes that are holding you adjust them in and tap lightly around the outside until you hear the drum ringing. If this doesn't work then grab a rubber mallet or dead blow and apply liberal pressure to the backside. Hope this helps, Tim
