Nimbus 36 unicycle cable brake
I welded on a little bracket to the back of my big 36’er unicycle frame to allow me to mount a cable brake:
The nimbus 36 frame that I use can run magura brakes, but I found I didn’t like them as much. They squeeked, and worse, they rubbed against the rim when going up steep hills. The cable brake has more clearance, and is also softer (which allows me to brake more often without worrying about it throwing me off the unicycle).

And the whole unicycle (before I welded the brake mount on I mounted it with two pipe clamps to make sure I liked it before I committed to welding it on):
