Ken is right about the radius of new shoes not matching worn drums. I put on new shoes and new slave cylinders on my camper several months ago. My pedal simply was sloppy and no amount of bleeding could fix it. I ended up double pedaling always. That means I stepped on the pedal twice and the second time I do it the pedal would be higher and the brake would be fine. The Pedal wasn'r spongy so it wasn't air in it. I knew it wasn't right but I could not fix it by adjusting or bleeding. Somehow a few months later now suddenly the pedal is right. I no longer need to double pedaling. I think what happens is the shoes are worn to a point that the radius now matches the drum. And the self-adjust is kicked in correctly. I should have filed the shoes when I put them on. It took me several hundred miles to break in instead. Of course I am not an expert and I could be wrong. Bottom line is my brake works correctly now and it has been that way for several weeks.
