The front bearings don't use shims to adjust preload, but rather a "Bottomless Teacup" shaped spacer which is(was) available in various specific sizes.
The brake shoes were zinc plated, but not galvanised, done electrolytically. If this finish has gone, a sandblast and POR15 grey will be the next best thing. Don't rely on just clean metal for the shoes. One of the major Achilles Heels of old CMPs is that moisture and dirt accumulate between the shoe and brake lining and the resulting flakes of rust that form cause the linings to bind on the drums, locking the wheel. As much rust preventative (not just paint) coating on the shoe as you can manage is GOOD for long term use.
