Thanks. I did open up the brake cylinder bleeder to help. I'd just assumed it was the brake shoes as it's so old. I finally figured out how to use the dead blow hammer on the hub and the push-bolts to loosen up the cone washers enough to pull them. Once they were out the hub did come out. Then I used a wedge attachment from a hydraulic body/frame kit from Harbor Freight to jam between the mast and the wheel. It worked to push the wheel off the spindle. That's when I discovered the shoes and drum look almost new. I get no movement from the piston rod at the brake cylinder so I'll be rebuilding or replacing the master cylinder and brake cylinders if I can source the parts. Thanks for the info, too.
