I haven't ever fooled with a band brake, but you will need a trunnion to go in that loose end of the band, a cable and housing, a lever for the handle bar and some attachment point on the frame for the cable conduit threaded portion to attach to. There has to be remnants of such a thing on the frame somewhere. If not, just weld a tab on there to get the job done. I would think the cable conduit needs to be mounted close to the anchor point for the other end of the band. I may be wrong. OldMiniBikes Warehouse has the parts.
