Adding to what's been said, be patient. Chances are, you do not have bad parts. Make sure the shoes are properly adjusted, then continue to methodically bleed the system.
A side note, not directly pertaining to your current condition- I would suggest replacing the brake lines with braided hoses, while you're working on the system. I had replaced the brake shoes on my 300FW (same brake setup as your Rancher). While they worked, the brakes were weak and spongy. I eventually purchased and installed the disc brake conversion- to find that the application of the front brakes were still spongy. Watching the original brake lines while applying the brake, I could see the hoses slightly swell. I was losing brake pressure through the hose swell. I replaced them with braided lines, and the application was rock hard. I am sure, that if I had replaced the hoses and stuck with the factory drums and shoes, I would have been satisfied with the factory braking (I don't regret the disc brakes, but my central issues was the hoses, not the drum brakes). Point is, it's worth the trouble and money to put braided lines on- you get all of the brake pressure to the cylinders.
