Hello and welcome to JustAnswer!
It's much more likely to be a collapsed rear brake hose. Brake hoses can collapse internally and not allow proper fluid flow though them. If the rear brake hose is collapsed then it won't be allowing enough fluid pressure to go to the wheel cylinders which will obviously cause the brakes to not be very effective.
What I would do is have a helper pump and hold the brake pedal just like when bleeding, crack one of the lines to the rear wheel cylinders at the brake hose or open a bleeder and see how much fluid comes out and how strong it is. Close that, have the helper pump again and then crack the line before it goes into the rear brake hose. If there is a difference in pressure and amount of fluid spray then the rear hose is collapsed and needs to be replaced.
I have great flow/ What I have is a pedal that feels there is air in the line and no matter how many times I pump it it doesnt get rock hard. It does get stiffer but not hard
To let you know it was a bad RABS. Your suggestions were in the order of good diagnostics. I didn't have the time to test pressure but I knew that wasnt the problem. Thanks for your assistance.
