ok, i have done many drum brake jobs in the past. but i recently bought this 87 cadillac deville with 89k miles on it. changed the front brakes no problem, hoses and rotors as well. i went to check the rear brakes since they probably are also in need of changing but the drum is seized to the hub. i got it to wiggle a bit with tons of pb blaster and going mortal combat style melee with a hammer on them, but i cant get them to come off all the way. any tips? first gm vehicle in my possession figured there may be a trick to these big beasts. im getting drums, shoes, springs, cylinders tomorrow. trying to save the hub if at all possible since it is still working just fine. btw do not have access to a torch or air tools.
