Have checked everywhere for leaks and found nothing. We have used up 9 32oz bottles of fluid bleeding.

Will It hurt any thing to loosen lines that go into abs system? Two pines going in and three oming out. Which ones can in touch

I know some GM actually have bleeders on the ABS section of brakes.

And then, there's this. The brakes evidently can be bled normally as long as you don't get air in the HCU (Hydraulic Control Unit) which shouldn't happen.
If the HCU is replaced or air is introduced a special tool is required to properly bleed the HCU.
"The brake master cylinder and Hydraulic Control Unit must be bled using Anti-lock Brake Adapter T90P-50-ALA and Jumper T93T-50-ALA. If this procedure is not followed, air will be trapped in the HCU which eventually leads to a spongy brake pedal."
