Robert,
What would you expect for evidence of scraping, and having found none, why
suspect the brakes versus maybe the tire or wheel or even the bearings? Is
it a 'feel' sort of thing? (like most of my observations about these cars).
One thing to consider is that some shoes have the pads placed asymetrically
on the backing plates. This was a problem I had and it caused premature
wear due to scraping. What would happen is that when I applied the brakes
when backing, it would shift the shoes a little, and they would drag when I
started going forward. Not enough to notice, but that's what my mechanic
and I figured out after long cogitation and a few beers. Try flipping the
pads (keeping the various holes in the right orientation). This would be an
easy fix, and it worked for me.
