MKATT,

Little confused here. Did you have pedal pressure when you bleed the brakes. I.E., did you pump up the brake pressure with the pedal before you open the bleeder valve? If you did, and successfully bled the system, but now don't have any pedal pressure, it would almost seem as if the master cylinder's main piston has a bad o-ring. Be a little more clearer on this for us. We all KNOW about the fustrations of projects going askew, it's happened to all of us, so work with us and we should be able to get you going.

Did you bleed the master cylinder before you installed it, sometimes it's difficult to get all the air out without bench bleeding. If you start the car up and push the pedal down, does it go to the floor? If so, any resistence at all? What happens if you pump it slowly several times, but only use about 3/4 pedal travel before you release and pump again. If resistence, is the pedal spongy? With the pedal held all the way down, have someone check for brake fluid seeping out at each caliper.

We need to acertain if the master cylinder is suppling pressure, and if it is where the blockage or open spot is. The brakes are really a fairly simple system. With out sounding like a smart alec, chances are you have a deffective part or just forgot a step. I know as this has happened to me several times.
If you see names like Foster, Aye, Herbst, Holst, Art, along with many others, make sure you drill-em full of questions. However be prepared to have answers that they can use, don't let the fustrations get to you. And NAPA parts are usually OK, some Volvo or European parts may be of a higher quality and last longer. But NAPA parts aren't normally junk. I view them as being midland to better in most cases.
Go and check out the steps I have giving you, then let us know what you find. I'll check back in a while.
