I think you're possibly misrecognizing the action of adjusting happening
as you adjust the shoes. The adjuster is a tapered bolt, with 4 flats
ground onto the taper. As you screw it in, the taper forces the shoes
outward.
BUT...because the adjuster has four flat sides, it also has four points.
As you rotate the adjuster, the shoes ride up on the points, and then
fall back down when they get to the flat part (where the wrench feels
loose on the adjuster). That's normal. You're not adjusting for the
peaks, your adjusting for the flats.
As you keep threading the adjuster in, the shoes keep getting spread
slightly. You run into the point where the shoes get pressed very
tightly against the drum on the points of the adjuster, but are still
quite free of the drum when they are down on the flats of the adjuster.
That's about where you want to be, just lightly scuffing on the flats.
