RE: 11A brake wount bleed
 

Did you bleed the master cylinder first? run line from the output back into the master resovouir and bleed all the internal air first. Then do the lines going to the calipers.

If this post was about the DISCO or ROVER I'd say ABS sometimes requires VACUUM to evacuate and bleed the system. ABS systems are different than the old/regular systems since there is a motorized/pressurized pump system that takes over when you apply brakes and the wheel speed sensors detect wheel lockup or difference between engine/trans speed and wheel speed.
