How do you keep the flux in place against the force of gavity?
Is there something like a ceramic sponge that can stand red heat and be used as
a carrier for the flux?

Usually you heat the brass rod and dip in into the flux and than just
braze it. If you are silver brazing you mix the flux with water and
paint it on the area to be brazed and go to it.
