I finally got the parts together to address my sticky rear brake. I couldn't quite figure out how to get it off, so I pulled the rear wheel. That, apparently, was a good thing. The bearings are very scratchy.
The brake piston was cruddy and scratched. I have a new one. I will also replace the hose. I will see about having a braided steel hose made.
Parts research shows bearings to be fairly generic. They are B6304ZZ small ball deep groove bearings.
Also took a look at the tire. Probably could use a new one. The original 1978 alloy wheel tire is specced as 3.50-18. Looks like that translates into a 100/90-18 tire.
