There's a good chance your new linings have a much harder braking material than your old ones. Before wasting a lot of money reinstall your old ones if they have decent lining material left. If that fixes the problem find a set of shoes with softer material.

That is the same brake bleeder that I am using, Yes longer shoe is on the back and adjusters are working. I sanded the drums with 80 grit to get the shine off, no improvement. I took the steel braided flex line off and reinstalled the rubber, no improvement. I reinstalled the braided line to get rid of the 50 year old rubber one.
Tonight I took the back of the proportioning valve apart and cleaned it. I did have some crud in it. I will bleed the brakes and bleed them again tomorrow.
