I don't buy the burnishing. I've never burnished brakes and haven't noticed a difference in stopping power. Even if burnishing has an effect, I don't think it will have the effect you're looking for.
You could have a wiring problem, or you could have an adjustment problem, or possibly both.
Here's what I would do in roughly this order.
Have a helper start the TV but leave it in park. Have them cycle the manual brake slide while you listen for a hum from each trailer wheel. If no hum from a wheel that brake is not working.
I have always hated adjusting drum brakes because the drums are never very round and you will hear light scraping long before they are adequately adjusted. I would adjust them to where you hear a decent drag. If you can turn the wheel by hand without really forcing it then they'll be okay. If you spin a wheel and let go and they spin more than 2-3 turns they are too loose.
Here's a few links to brake discussions.

You might have to run new heavier gauge wires to each brake. It will probably make the biggest difference out of all the changes. There was a post on here a few years ago by user Spike99 where they were using what they called star wiring. In effect it is parallel wiring to the wheels instead of the serial wiring that most manufacturers use. Here's a picture.
