Ever had self adjusting brakes overtighten?

The brakes were replaced one side at a time - so the adjusters were not swapped. As for secondary shoe on primary side....please educate me on which is primary and which is secondary. I called myself putting new shoes on the same way the old shoes were setup. I'll need to pull the wheel and look to verify the primary vs secondary shoe location. I'm looking at a picture in the service manual of the left rear wheel/brakes. I recall looking in the manual for guidance on which shoe went where and only found the picture for the left rear. I almost hope I screwed up - that might explain why the parking brake wasn't holding well enough on a steep hill.
The primary shoe is always on the front position and is the shorter of the two shoes. Note the shorter shoes on the outside.
