Latest on the bleeding trouble with this sec modle, found that the master was infact the problem. I broke down the lines from the master to the ABS and of course no fluid, so I removed the master and found that the rubber( the seal for the fluid reservoir) had softened just enough to cover the hole in the front of the master cylinder. there for no fluid flow. after that we had good flow and no brake trouble. though I did have a front calilper sticking causeing a drag. I suppose for those who never think of changeing or flushing the brake system you can exspect this type of trouble.
