Were you vacuum bleeding? If so, you will pull air around the bleeder screw threads 99% of the time. While it will look like you are getting a LOT of air in the system, you will have no more than a tiny bubble at the bleeder screw when you are done. The suggestion of greasing the screw is a good one. Applying a little RTV to the threads WITHOUT removing the bleeder will also work. If you do vacuum bleed, just find a helper for that last little pedal push to finish off each caliper.

And, yes, you should see new-looking fluid after a thorough bleed. The biggest thing for success is to start with a clean M/C. Suck out the reservoir & wipe it out with a clean rag then fill it with fresh fluid before starting your flush. Otherwise the muck at the bottom of the M/C will continue to mix with your new fluid as you run it through the system. You'll eventually get clean looking fluid to the wheels, but it wil waste a lot of fluid.
