Do you have room to install a collar, with a small disc

The collar would probably be easy although there is
nothing available
off the shelf that I'm aware of. The difficult part would
be creating
a secure attachment point for the caliper. Given the
forces involved,
the caliper itself would need to be hydraulically actuated
like a disc
brake.

Something like a handbrake on a forktruck would work.
