Pondering a way to get a disc brake on my in-progress 125cc Lifan bike. It has a SA front drum already but, I wanted to upgrade the rear. Am going to run a cruiser wheel with chain only on the left side(no pedals) This left the coaster brake pretty useless. Long story short I found that a standard 6 bolt disc will pop over and center on the coaster sprocket hub. I can mount it securely to the hub and fab mounts no problem. Just wanted some thoughts on what the function might be like. On applying the disc brake the slowing of the disc should also apply the coaster. I guess actually the coaster will be doing the stopping and the disc applying the brake, right. If the coaster fades in theory the disc will still stop, but the coaster would no longer slow the wheel? Maybe its just an unusual way to apply a coaster. Looks like it will work well on this particular build though(becomes a hand brake).
