im no professional but im curious why you want to run dual rear brakes? from my understanding thats not gonna help you stop much better than a single rear brake..

It looks kool but weight transfer deloads any back wheel so there's no advantage vs a good conventional rear brake. Fab Kevin makes some nice kits with dual calipers on the same side which make much more sense than a sprotor (which is a wear part and wear parts are best kept cheap and standard, though many choppers won't see enough miles to wear out sprockets).

Disc plus sprotor is a lot of extra shit (plumbing and mounts) but do whatever floats your boat. Since it's a rigid the hard lines will be easy to manage as no flex hoses are required unless you like them or want them for maintenance convenience. Hard lines are cheap too.

Choppers aren't about function, they sacrifice function to be folk art but decent brakes can prevent becoming a meat crayon (and no matter how good your back brake is it doesn't produce the same measured result as the same brake plus an effective front brake). All braking is objectively measurable.

The op needs to chime in but lots of duel rear setups are to allow a handlebar operated brake to use as a hill holder with a foot clutch. I think that a foot clutch with a locking lever is a cleaner solution. A single caliper operated by two master cylinders requires a shuttle valve and the occasional pump up, never very satisfactory.

My 50 idling in gear to prove to a friend that it was possible. I think a cleaner solution to not having enough legs to hold the bike up and the clutch n brake.

I just can't see two rear brakes looking good. A good sprotor will stop the rear just fine.
That's just my opinion. I did run a sprotor on my pro street that worked great.
