I use the Motive Power Brake bleeder. add brake fluid, and then pump it up, open the bleeders, ( R/R, L/R, R/F, L/F and then the Clutch line.
As Stevo said use air pressure, this would be I guess using a Bug Sprayer or the Motive unit w/o any Brake Fluid to flush the system except what is in the Brake reservor. then you have to keep an eye on the reservor so you don`t run dry and add air to the system.
here is a link to the one I have,comes with the cap to screw onto the MB reservor. I added a Swivel where the 2 brass fitting screw together, or the hose will get twisted screwing them together.

There are some threads on making a pressure bleeder using a Bug Sprayer.
