Anyone have a suggestion on removing a hung up rear brake drum? I removed one side by hand as you should be able to. I can't get the other side off. I have the adjustment knob all the way in. The drum spins freely, but I can't pull it off by hand. Never had it off before. I tried hammering it from behind with a block of wood but no results. Is there such a thing as a drum puller that can be borrowed from the likes of O'Reilly or Auto Zone? Thanks.
