I'm very sure they're on correctly as you can see in this picture of the left side..only thing is the bottem spring is the wrong way around, but I changed that before completing the brakes.

I know you bled the brakes, but bleed them again. You used the vacuum method and if you didn't use the pedal method at all there could be air in the master cylinder, which should have been bled also.

thanks for the feedback and I guess my root-cause analysis will look like this:
first testdrive without the vacuum connected to the brake booster, just to see if it does anything, then reroute the plumbing, then take out proportioning valve..and if all that does't show the problem, I'll set her on fire and drink myself to sleep
