That's a 1956 AMF bike. Roadmaster bikes were Cleveland Welding Company until bought by AMF and moved to Arkansas around 53 or so. Thanks for posting your serial number, it IDs your bike as 56 and shows a straightbar frame with forward dropouts. I'm trying to find when they went to cantilever, I think 57 but haven't seen solid proof. I would keep your paint job as it because of the upsidedown emblem, that's an oddity and the pinstriping looks good. A coat of wax may make it shine, just be careful about the emblems and striping while cleaning it. That would have had peaked fenders, so those aren't original. The braces look custom made and heavy duty. The seat looks like an original would have.
Beat me to it@Falstaff is a member here...no connection to the above building that I know of.
Should work...spacing will need adjusted. Anything that connects the brake to the hub...a disc front hub with an adapter would probably work. Band brakes are big in asia, front and rear...and used to be sold as kits in the states bitd as auxiliary brakes. I don't know how those kits attached to the hub, however.
That's what I'm using front and rear on my bike. Band brakes. They are both rear wheels.
