Self adjusters keep overtighten

Your drums look to be at max diameter or more maybe (many cuts or excessive wear). New shoes will then have a much smaller diameter or arc. Under firm application the shoes spread to match the larger arc of the drums, causing too much pull on the adjuster cable, tightening the adjusters too much. If you install new drums or have the shoes arc ground to match the drums, I believe your problems will be over.

Also yours are the old style adjusters, pre 1969 I believe, which turned the star wheel on the down stroke. The new style adjusters, used until the demise of drum brakes, adjusted the star wheel on the upstroke and proved to be more reliable (not interchangeable). Adjusters usually have L or R stamped on the end of the stud under the free spinning end.

New style bendix adjusters just for reference:

How do you tell that they are at max and have excessive wear? Is it from the thickness of the lip that the arrow point to? Running my finger around the surface it felt even and i did not feel any cuts.

And yes, I have the old style adjusters. I guess they changed them for a reason.
