That brake drum looks to have little or no wear on it. Some manufacturers have allowed for slightly thicker brake shoes to allow for well worn brake drums, which most trikes have. You don't even have a wear lip along the edge of the drum which most trikes will have when the drum is worn down. You just have to break those shoes in somewhat and you will have lots of wear in that drum it looks like. You just have some very nice looking low wear pieces. I wish I was so lucky with some of my trikes. LOL
