Default No Breaks

I have a 2003 Pontiac Grand Am with no working break pedal, it goes to the floor. I replaced one rear caliper, all break lines, and the master cylinder, blead all the lines several times, and the break pedal goes all the way to the floor. Does anyone have any idea why there is still no resistance in the pedal? Also, nothing is leaking.

1st off, it'* actually brake(*).

When you were bleeding the brakes, did you get any fluid flow at all? How did you go about bleeding them?

your best bet is to pressure bleed them, starting with the corner furthest from the MC, working your way to the closest. Also, if you didn't bench bleed the MC whenyou put it on, you may need to take it back off and do that first.

Before the work was done, was there a massive loss of fluid?

I assume this has ABS...did you bleed the modulator?

What is the process on bleeding the modulator? Is that the step where you can either use a tech 2, or go out on a dirt road and force ABS actuation repeatedly?
