I checked the center pin on all four wheels as part of the adjustment following reassembly, ensuring the spacing between lining and drum is as even as possible. The drums have an inspection port for a feeler gauge.

There are no springs around the drum and no obvious provision for them. I thought those were intended to aid cooling, not for noise. I would think a spring would amplify noise, if anything.

I cleaned the linings on that wheel. There was already quite a bit of dust buildup due to the chattering shoes and they had turned from tan color to charcoal color. After cleaning them which restored the tan color the wear didn't look nearly as uneven as before they were cleaned. I haven't taken the car for a drive yet to see if it makes any difference.

I think the lining material is already at least partially chamfered at the ends but I'd have to look at them again to be sure. It may be only one shoe is or just the leading or trailing edges.
