I'm looking at the different thicknesses of the still attached linings versus the rogue ones. Could something in that brake like a wheel cylinder, be binding up which caused the brake to overheat and shed its lining? Doesn't look burnt, but then again we can't see the drum from the detached side, either. The detached shoe looks pretty shredded, the holes wallowed out too big to reattach.
