Not sure what kind of bike I have. When I was a young lad I pulled bikes apart. This bike my parents had in one of their barns. Everything looks normal until I got to the rear end.. It looks like a clutch pack or some thing... Though I know it's the brakes. Not sure how to clean it. Should I replace it with some thing dif. The rear rim is iffy. Kind of rusty a bit. Painted rim. If anyone know the kind and year that would be cool too. I'm thinking a coast king???
