Hmm, i've got a syringe type setup that I think I bought for doing it on my motorbike once but never used it.

Any reason I can't use that to pull fluid/air out in the same effect as these other things? Provided I lock the bleed nipple off when I empty the fluid out, there will still be fluid in the hose so I can't reintroduce air into the system.
