Good news:

I went to the local junkyard and pulled a brake booster and master cylinder

I power bled the system and braking is much better than it was before.

The pedal feels more solid.

I believe the problem stemmed from the fact that I had a 500E master cylinder hooked up to a 190E 2.6 booster. The 2.6 booster has an amplification factor of 4.5 where as the 500E booster is 5.6.

I do have a concern about my front calipers / rotors:

There appears to be a blue streak on the rotor (from getting hot?) and the rotor is heavily rusted (or atleast to me it is) and its only 6 months old...Its a PBR rotor by the way.

I am wondering if either my rotors are just crappy. I've got brand new pads on (textar)... that or my calipers are just "weak" and not really applying them hard?
