I am looking for a nifty little instrument to clean out each little hole that has been drilled in the break rotors. I have been using a drill bit to ream the holes out but probably need something that will really clean them out. I know this sounds crazy but there sure is a lot of break dust that comes out. Any thoughts? Thanks,

I never thought about it, but maybe a brass firearm bore cleaning brush? They come in nylon also if you're interested. You just buy a handle and the brushes are pretty cheap to replace.
