Frozen rear brake drum

Notice holes I used to try and get PB Blaster in. Waiting a day. No movement.

I took the axle nut off, and the outer bearing to give some movement to the assembly.

I cut a square hole in the drum with a grinding wheel. This one hole gave enough access to pry the two shoes with a crowbar. A good facemask would have been in order, as the old shoes probably have asbestos.
