>Brake shoes? what's that? Where you have spring-loaded parking brakes, you essentially have disk brakes, or, if you have brake shoes, they rarely wear out… remember, parking brakes…
The parking brakes on the Amtrak locomotives I mentioned use the same brake shoes as the regular brake cylinders (tread brake units).
