Jack, thanks for refreshing my memory and correcting me.

I'm curious about your opinion on hardening the friction surface of brake drums. From what I'd read years back the centrifuse cast iron surface was specifically selected for optimum frictional properties with the linings and a more hardened (closer-pored surface) would give poorer brake performance. Steel drums gave way to the centrifugally cast drum surfaces and that was considered a very major advance in brake technology. Any thoughts on that?
