Hello gentlemen, I've been a hearse owner for a long time. My first was a 1969 superior cadillac combo. My next is a 1965 cadillac superior. It's time to do the brakes and I'm having the hardest time trying to remove the rear drums off the axle. I really have tried everything. Drum pullers, torch, port-a-power, etc. The shoes were backed off. Yes, i did take the nut off too. What am I doing wrong?
