I love coaster brakes. They allow for a completely silent ride, and for a beautiful streamlined look. Also, they last forever with virtually zero maintenance. Read the post"coaster brakes rule".
Here is a single speed Bendix coaster hub I bought on Ebay. It's really grimy, and not very pretty to look at. I'd better clean it up and tune it before I mount it on a wheel:
Take is apart, keeping the parts in order for easy reassembly, and clean with a small wire brush, steel wool and a rag. Remove all the old grease. Polish those parts until they look as new as possible:
Grease it back up. I like to use high temperature truck grease; it allows for a smooth silent functioning of the hub:
Put it back together, adjusting the pressure on the bearings so that it runs smoothly, but doesn't jiggle. Make sure the axle is centered:
Here is where this one's going:
