I had the same problem with mine when I switched the calipers about two weeks ago. I later found that there was air at the master as well as at the ABS module. Corrected it by staring at master and pumping pedal and holding. Then cracked the fittings, just like the bleeder valve. Then move to the four fittings atop the ABS module. Then did the calipers again and worked great.

It's fixed! I am relieved. Thanks for all the input. I pressure bled again today at 30psi starting with the right rear, hardly a trickle with the engine off. Tried ignition on, same thing. Tried engine running, same thing. Pumped the pedal about 15 times with the bleeder screw open and the Motive connected (full of fluid, works great to keep the master cylinder full by the way), and got more flow. Did all 4 wheels in the correct order this way. Then did all 4 a second time with the engine off, all electrical off, and 30psi pressure only, no pumping. Started again at the right rear, very slow flow so I went and had lunch. Came out about 5 minutes later and to my surprise the Motive was down about an inch from where it was, and the bleeding hose into my bucket was full. Did this to all 4, went through over 3 quarts of fluid. Put it back together, and a quick test drive revealed a rock hard pedal, just the way it should be. The pressure bleeding with everything off certainly works, the rears just bleed much slower than the fronts. I think I just didn't give it enough time last time. Part of being able to do it this way though is putting the fluid in the Motive. Thanks to everybody for the quick help.

I don't know what finally made a difference, but glad to hear you have a nice firm pedal now!!
