Was attempting to do the rear axle seals and brake pads on 47 8n.
Backed off the adjustment screw thru tiny hole in back plate.
Removed the screws to hub and pulled.
Got 1/4" and stopped.
Pushed it back and pulled again and nothing. 1/4" and stopped again.
Took dead blow hammer and beat the crap out of the drum and backing plate.
Nothing.
Looking at 4 nuts holding brake assembly to axle housing.
Can it be removed as 1 piece and taken apart that way?
 
Screws are removed. It only had two.
I saw 4 holes in drum, but only 2 had threaded holes for the screws, showing thru drum.
The drum moves 1/4" and stops.
Brake peddle is sloppy loose too.
Thinking the drum is grooved and pads are seized.
I used my cold chisel on screws.
Thinking remove the whole brake/hub assembly off housing.

IF" you could do that, then as I see it, you still have the same problem of not getting drum ridge over shoes, except now the whole assembly is not attached to any substantial structure to hold it in place while you beat, pry, etc.
 
It sounds as you might need to keep adjusting the brakes so they are as loose as they can be. It sounds like the shoes are catching on the wear rim in the drum.
 
If the brake pedal is sloppy loose, then it is probably sinking down towards the foot floor plate. This will cam out the brake shoes. So block up the pedal from the foot plate, and hope the brake springs are still intact to pull the shoes together. If there has been a oil leak into the brake (very common), then the baked oil may be causing the shoes to stick tight to the inside of the brake drum, not allowing you to get the wear ridge on the drum to pass the greasy shoes. You may need to spray some solvent (old gas??) into the brake area to get the grease thinned down enough to allow the brake springs to retract the shoes. Sometimes the adjusters are rusted tight and then you only think you are loosening them. Try to peek through the adjuster hole to see if the adjuster is really turning. Loosen it fully. I have an old brake drum lathe I use to cut the wear ridge out of the drum before reassembly. See recent post about turning brake drums. They are fairly thin compared to automotive drums.
