If you're going to add a brake, why not just a normal front brake? This has several disadvantages:
Still only brake with the rear wheel which is less effective than the front.
Subject to single failures - broken chain or loose chain derailment leaves you brakeless.
Custom design so replacement parts may be hard or impossible to find.

A super-stopper brake on a wheel that can only slow you down? (Do the math. It takes fully twice the distance to stop with just a rear brake.)
And - how to make the ultra-simple, clean fix gear high tech and complicated. (I confess, I do run traditional rim brakes on both wheels, but that has been done on road fix gears for at least 90 years.)

I remember seeing that ages ago, it is from back in 2008. The bike is a Sycip, custom build for a trade show. Here is an online article with a slightly different angle of the disc brake. If you do a google image search "Sycip crank arm disc brake", there are other pictures online.

I’ve seen that one before. Wasnt too impressed. Would have been slicker, but just as stupid, to let the chain ring do double duty as brake rotor.
I wonder what tooth count would equal a 140 mm rotor?
As long as you manage to avoid contamination, a combined sprocket/rotor would give both a clean rear and a rear brake. Perhaps internal routing to top it off.
