Jerry, that was very good. I'm a brake pro specializing in the restoration of vintage brake parts, and the only thing I would change is: *some* wheel cylinders have a spring with a cup expander on both ends instead of *most*...it depends on the engineer who designed the rubber cups, and in my (rather considerable) experience the expander type cups are in the minority.
Scott, new cylinders are often but not always the best option. Depending on the cost of the new parts and the length of time one expects to own the vehicle, sleeving wheel and master cylinders can be more economical, and definitely offers longer service life, than new cylinders, especially the cheap off-shore repops that are so common in the vintage parts catalogs. Good quality Stovebolt wheel cylinders are still available at reasonable prices, but most new Stovebolt masters cost considerably more than the price of sleeving and a rebuild kit and won't last nearly as long.
