What I found a useful alternative was to bleed the abs unit manually.
Make sure that you have activated the abs first (I suspect that it might retain some air if not activated). Then place some absorbent rags under the abs unit (you will not be able to use a container and you don't want nasty brake fluid on your inner wing).
Then get your loyal assistant to apply some pressure to the brake pedal and, while the brake pedal is under pressure, slightly loosen the connections on the top of the abs unit.
You may have to do this for each pipe in turn, but it should remove most if not all of the air.
