just to complete the posting,

put back the rebuilt caliber a week ago, connecting to brake hose, with said 26 ft lbs.  I had to keep tightening the screw, 1/4 turn at a time, 30 ft lbs, still showing air leak.  The screw is after market Duralast not the original one as it broke.  This is probably why the final torque was 41 ft lbs.  Bleeding with a in-paitient assistant finally worked.  Braking is as hard as I can remember, and had driven a tank with no issue.

O'reilly was kind enough to refund the Duralast caliber.  I said due to different brand, the brake was soft.
