The brake drum has a 36mm castle nut the is held on with a split pin. This has been removed along with the adjuster bolts, brake pads and retaining springs/ washers.

I just placed the brake ajuster bolts in the bottle, filled it with white spirit and shook away the grease. After a few minutes of soaking and shaking, I wiped with a rag.

Didn't do much to the brake pads. They look like they have a few more miles left in them so they are going back on. I'm sure these brake pads aren't made of asbestos anymore but I'm not sure if they are contaminated with p[revious brake pad dust.

The adjuster bolts, cleaned greased inside and back in place.

I put the springs on the brake pads and located the tops into the cylinders first. Then I stretched the lower parts into the adjusters. Note the adjusters have an angled edge in the recess where the brake shoe sits. They need to be mated up or the drum will be tight to get on.
