I had the same issue on an alloy reservoir I bought off of E-bay and fitted to my Fireblade after carrying out a top yoke conversion.It started off with a misting on the rubber hose on colder days but then within a few weeks it seemed to be happening regardless of the weather.I tested the fluid on the outer of the hose and it was indeed brake fluid. It seems the rubber hose that is supplied with most of the stuff from China is not actually suitable for corrosive liquids such as brake fluid.
I bought a length of hose (graded for fuels) from the local motor factors and fitted that. Never had a problem with it after that.
