OK guys, I am about ready to just cut this jetta into pieces and sell it for scrap!!!  The brake problem STILL eludes me.  Just as a reminder, the car has Scirocco rear disc brakes and Cabriolet (rabbit) front discs.    The story so far: 3 master cylinders (four if you count the original that was in the car) so I know the problem doesn't lie there, new rear hard brake lines, new brake proportioning valve, removed and cleaned residual brake pressure valves - they work fine, removed and rebuilt both rear brake calipers - they operate as they should when the brakes are depressed, I have bleed nearly 2 gallons of brake fluid through the system - no air left, I have visually inspected all hard lines and soft lines for leaking or swelling - nothing is apparent but all four wheels seem to bleed just fine with good pressure, but the system is still very mushy and the pedal will go to the floor and finally, just to really make things odd, when you start the car and the brake booster comes on line, you loose ALL pressure in the brake system and the pedal will go directly to the floor with NO resistance!!!!!  I have done a lot of brakes in a lot of different vehicles but I have never had one that kicked my butt like this one is doing.  Out side of replacing ALL hard and soft lines, anyone got any other suggestions before I call it quits and just part the #$%@# think out?  Hayden
