Safety and patience are critical here.
I've been there. The right rear on my '62 was the most difficult of any I have ever done. The heaviest duty tool available should be used. There are many grades of this tool. I have broken four of the lesser ones.
Don't give up, and find a stronger hub puller. You are frustrated and jumping to conclusions. It will come off. Safety and patience are critical here.
I am having an impossible time removing the Right rear brake drum from my '55 Newport. I did use a proper hub puller and removed the left brake drum, with some difficulty. The hub puller bolts to the drum, has three arms that go to a center disk, and has a center shaft that pushes against the axle. The center shaft has an alignment pin to keep it centered. After many attempts to free the right hub, the tool broke from the hook part of one leg stretching open. The puller is now useless.
I found a friend with a Snap-On hub puller and have been using that one. It does not have a centering pin and the center shaft moves slightly off center when hammering. The tool is much stronger, but the right hub/drum does not budge. My friend and I have been hammering both the puller arm and the axle. The puller has caused some indentation on the axle shaft.
Can anyone share their experiences at dealing with really difficult brake removal issues that might help solve this problem? My next step is to apply lots of heat to the hub, but I have concerns regarding the flammable oil and grease as well as causing damage to the hub. Does the axle have to come off and taken to a shop? How would a shop proceed from there?
Does the brake hub/drum have to be destroyed and a replacement found? Even then, what is used to cut/torch the drum. Yes, I am getting desperate here.
Any suggestions would be welcome.
Thank you;
