Is that a saw blade or a clutch lol

do you have the rest of the brake?....it looks like a band-brake to me, or is it internal expanding?

That's a tiny brake! It looks more like the size of a clutch. More pictures in context, especially how it was mounted originally, would help. It didn't originally come with teh Predator, right?
