Howdy! Best of luck with your brake work. I had one on my WD that like to drove me crazy. We sprayed it with every penetrating liquid known to man, used heat, beat it with a half-dozen different sized hammers, and even tried freezing the pin in dry ice to try to get it to shrink up and gain us a little room. Nothing worked. We eventually cut the brake drum into small pieces so we could take the axle housing off that side ( won't come off until you do ) This pin was stuck on the inside( rear differential ) Once the axle housing was off we used a pipe wrench to force it to turn until we could twist it out. What a mess! Got a couple ideas that I picked up the hard way. First, on my WD there was a small inspection holeat the bottom of the housing the pin runs through. Stopper that sucker up and fill the brake compartment full of you favorite soaking stuff ( WD40, Marvel )Second when you get it apart, LIGHTLY grind the pin down where it seized, it will be easy to use the old pin as a model. This will not hurt the action of that pin as all it does is provide a pivot for the brake shoes. Last coat that sucker with never-seize before you put it back. Your great grandchildren will be able to take it apart with a pair of plyers. Best of luck, it can be a bear of a repair.
