Curt,
You know, there is a rachet action mechanism in those calipers! I had forgotten about it over the years. They are supposed to self-adjust, but I was under the impression that it only adjusted the hand brake pads. I will dig out the manual and see if it is supposed to adjust the main brake pads, too. I use my hand brake all the time, but he adjusters may not be working. Thanks for the idea.
