Rear port does not send any fluid through until rod is almost at the end of it's travel.
Thinking there may be a lot of air the rear port, I repeated pushing in the rod 10 times with the same results
This looks like a bad master cylinder to me.
Take it bake to AZ, and explain it to them, becuase it's new dosen't mean squat.
