Air in rear brake

I have been trying to bleed rear brakes but always have air in brake line. Noticed brake fluid coming out of brake fluid resivor. I could really do with some advise what is causing problem.

Have you bled the load sensing valve?
Underneath in center just forward of rear axle, (well it is on mine).
