If you have a Miti-Vac hand pump kit you can draw fluid (along with any and all air bubbles) through the system and out the bleed screw very quickly and easily. The best DIY way to bleed hydraulics by far. You can buy this tool at most auto parts stores. I use it to bleed or flush new fluid in car brakes quick and painlessly by myself. Bike hydraulics are a few minutes work and you're done.
I bought a Miti-Vac from Sears last weekend and did my fluid....the fluid looked like chocolate milk
First, I took a turkey baster and sucked out the old fluid, replaced with new fluid. The bleeder is located on the left side by the shift lever...connect the hose, take an open wrench to the top nut not the bottom (bottom nut loosens the bango nut). Create vacum by pumping the tool to about 20psi, open the nut and suck fluid through. Keep doing this until the fluid is clear.
