Hy timbuk, I think we have at least a couple of problems here. If you look at the part of the shoe which contacts the adjuster wheel it is not sitting square, it looks like if you flip it over, it might sit more square to the adjuster, Also those springs don't look correct to me, and my brake catalogue shows a different type of spring for that year, and those springs are shown in a picture of the Bendix self adjusting brakes. My parts book also shows a heat shield over each wheel cylinder. Also when you are bleeding your brakes, adjust them all the way up first, hope that helps.
