juice brakes drag when rotating - only one way

[benbuilder]

I posted this on the Jalopy Journal, but felt like i should post it here also.
I have a 1931 model A truck I bought that needs a lot of work.
I’m going through all the mechanicals trying to make it road worthy.
It had juice brakes when I got it. Non functioning.
I replaced all the brake lines, hoses and cylinders. I also replaced the master cylinder.
I have bled all the brakes and I have good brakes everywhere.
I went to adjust the brakes and noticed that the rear brakes adjusters were not moving 1939 to 1942 style.
So I took the rears apart, cleaned everything up and installed the components.
I am now ready to adjust the brakes.
On the driver side rear, when I turn the drum as if I’m going in reverse, the drum rotates very easily.
When I try to turn the drum as if to be driving forward, there is a lot of drag.
I can go backwards with no drag.
If i remove the drum, the axle spins freely both ways.
My adjusters are not the problem, they are in a loose position.
I don’t believe it’s the wheel cylinder holding out the brakes because I cannot pull the brake shoes in any closer due to the fact that the emergency brake sets the spread distance of the brake shoes just by design.
I have done some searches but did not find anything.
Thoughts? Thanks.
