The way I used, get a bucket of water and antifreeze, jsut deep enough to put the lever in, take the bleeder out of the lever, and take the bleeder out of the end slave cylinder. With the lever submerged, depress the lever, then hold your thumb (or have a mate) over the slave cylinder, release the lever, wait a few secs (so all presure is relieved) then take your thumb off and press the lever once more, repeat this as many times as you lie, but try to do it about 20 or more for a proper flush! Then finally squeeze the lever, put the plug in the slave cylinder, release the lever and do the same up top. Has worked well for me. But i have just bought the bleed kit to save me this arsing about next time, plus i dont have a giant bucket of oil which i want to put in
