Bleeding brake system

[Wolf328]

I just installed a new RABS unit and I'm trying to bleed the brakes. I'm not getting any fluid from the rear wheel cylinders, or the rear brake line splitter on the rear differential. Any ideas on what might be going on?

By RABS sensor, are you talking about the Rear ABS sensor?

Yes. The valve on the frame under the driver door area. One line in and one line out and an electrical plug.
