I have purchased 2 power bleeding devices and I still cannot get this brake bleeding thing down.  No matter what I do I never get just fluid out of the bleeder valve, there is always lots of air. I  assumed that the connectors were allowing air to escape on the sides so I even tried different size hoses to attach to the bleeder valve.  Still no use,  its always about 50% air coming out and never stops.

Suggestions appreciated.

(BTW, not sure why but my posts have been taking a long time to propagate back out from the server...)

Thanks,
