The only drawback I see is additional wear on the pads and rotor of a single-disc set up, but there are lots of them running around out there and they work. Terry seems to have built a few of these and I am sure the pads, calipers and rotors are designed to last. I wish I could get a single inboard brake on my Lehman belt-drive setup, but I would have to completely rebuild the diffy housing to do so.
The small differentials that I have been into are very strong. Lehman uses one of "unknown origin" that no local auto dealership, or mechanic can identify around here. I think it came from some un-imported foreign compact vehicle.
