We have changed the pads, master cylinder (twice) and have turned the rotors...they still won't bleed up. We have no pressure in the lines at all and cannot get a brake. Any suggestions.

It is a Monte Carlo 99 model V-6 3.1L.

It sounds like you have a bad ABS motor assembly. Have you had it scanned with an ABS capable scanner?

I know it's sort-of an old thread, but was the master cylinder bench bled before it was installed? It most definitely has to be..

are all of the vaccume hoses ok, check all of them
