how hot do drums get?

[Sovereign]

I recently redid the rear brakes on my 86 C10. New Bosch shoes and had the drums turned. It's the light duty setup so 11" drums with 2" wide shoes. I've put everything back together and adjusted the shoes so they were dragging just a little. I could easily turn the wheels. It's not as free spinning as the fronts but I'm not fighting to make a revolution.

After a short 4 mile drive with minimal braking, my drums were getting up to 100*C while the front rotors would be at 30*C. So I adjust the screws for the shoes in a bit and go for another drive, same issue. This next time, I turn the adjuster all the way in on one side only. Go for a 5 mile drive and that drum is at 60*C while the other side is 150*C. This was expected and what I hoped would happen.The problem is now that the pedal is soft since the one side is adjusted in so far.

What am I dong wrong? Every time, the drag on the drum is what I would consider minimal but they were still getting very hot in a very short time with minimal braking. The front rotors are always significantly cooler after my test drives. I can adjust the one shoe out a small amount or just back up a few times and press the brake to self adjust the pads. I'm afraid I'm just going to be right back to the high temperatures in the drums again. It's been a long time since I have worked with drum brakes, but I don't remember them getting excessively hot. Other than the heat, the brakes felt and worked great. I'm concerned something is not right and will cause serious issue on a longer drive.

I have the shoes with less material facing towards the front of the truck. The brakes I replaced were good. I only did the brake job because I got gear oil on the pads changing the rear gears. The one difference I have noticed between old and new pads is the friction material on the old pads that faced forward didn't extend so far up towards the top and bottom of the shoe. From what I am seeing for shoes online, that seems odd and what I have on now is correct.

Any thoughts?

Thank you
