Thanks for all the advice guys. Both the shop and myself had used a Motive pressure bleeder, and the shop has a GT1 computer and while they bled the brakes, they had the computer set to bleed mode which ran the abs pumps to get any air out.
I didn't bleed them with the car running, as I didn't think that made a difference, but maybe I should have tried that. If the shop had it on the computer, then they must of at least had it on at that point.
I also let it sit with the pressure bleeder on and it held at 10lbs for 2 hours, so I have to rule out other leaks or bad calipers.
Also when I installed the master cylinder I bench bled it before I installed it, and then after I installed it, I cracked the lines where I did get some air out, so that was good. But the pedal is still bad. Worse than it was before I replaced the master cylinder.
I already purchased the used DSC / abs unit, so we'll see if that was the culprit. The one thing that was mentioned was the master cylinder not being installed correctly.
I did it myself and I'm by no means a pro, so maybe I screwed something up... Although it seems pretty straight forward. I just put the rod into the booster and lined it up with the piston on the master cylinder and then bolted it in. Who knows. If this dsc/abs unit doesn't work, I'll have them reinstall the master cylinder for me.
One thing that was mentioned was to open the lines before and after the pump to manually bleed any air out. I did not do that, and I think it would have been a good idea. But wouldn't just bleeding it normally with the computer set to bleed mode accomplish the same thing?
The shop it's at is Auto Europe in Birmingham, MI. They come VERY highly recommended so hopefully they can help me figure it out without sending me to the poorhouse.
Very frustrating! I'll keep everyone in the loop as things progress in case other have this challenge. Wish me luck, and if anyone has any other ideas, let me know.
