48 bigtrucks,
After thinking about your post I looked at my picture again and realized it's misleading, I've screwed the adjusters in a lot more after I took the picture. Sorry for the inaccurate picture.
However, I realized that I was automatically adjusting them equally on both sides, and when I checked the as yet "untouched" brake on the other wheel the adjustment is definitely not equal on both sides. Seems like somebody said something about Hucks not applying pressure equally on both shoes. I'll have to experiment with the adjusters tomorrow.
