winmutt,

i do some off roading, so its crucial our brake fluid is changed correctly and somewhat frequently. take a look at my writeup here: http://4runners.org/writeups/brakebleed/index.htm

a couple of key tips:

1) two people always seem to work better
2) baaarely crack the bleeder screw. you dont have to see alot of fluid come out.
3) have your friend pump the brakes but have him put a wood block behind the brake so he does not damage the MC piston
4) when you are finished with one side, have your buddy pump the brake once more, have him hold it, and then you tighten the bleeder valve. if he lets the brake go, air gets sucked in.

me: lots of trial and error and that writeup above is the culmination of some very frustrating attempts over two to three weeks
