Yep, I just verified accumulator pressure. Still holding steady at 15 bar.

There are several steps we can take to improve our ability to bleed the system of air by adding bleed valves in certain locations. I stand by my concern that the master cylinder can’t be bled unless the hydraulic connection ports are as close to 12 o’clock as possible. ZF specifically states that if the cylinder can’t be oriented properly then the cylinder must be bled properly then installed in its operating location.

I have both cylinders internal pieces and don’t believe that flowing fluid through the system using the MINIMESS fittings will rid the system of all air unless bleed valves are installed at key locations such as at the accumulator top, rear cylinder side that centers the tags, and the front cylinder’s ports. By adding additional MINIMESS and using a multi step process of bleeding, there is a better likelihood of ridding the system of air. 

My front cylinder was re-oriented and the system has been serviced so many times that it might have less air in the system than before. I’m happy with the current performance but the game changer was getting all three axles working together. 
All the accumulator does is ensure there is ample pressure in the system to keep the TAG straight going down the road. That a simplistic statement but and yes there’s benefits when the rear tires work in concert with steers while maneuvering but if you don’t have a good straight ahead rolling bus… the rest is useless.  

We’ve figured out the ZF RAS mysteries and now the mission will be improving our system.
