Hey LarrBeard, I never answered your questions:

Drums turned - no idea - they look good to me.
Brake linings - new on the rear, front look good probably 1/8" thickness and not brittle

Front eccentrics were not working properly, so I replaced one and the bottom adjusters were frozen - I tore down the front hubs this past weekend and have cleaned everything and will re-assemble and try it again. It is probably a combination of eccentric/bleeding issues.
