Ok, here's the update...

Replaced both front brake lines with new Napa ones, still having the same problem. We did notice however, that when the car is off, there's no problem building pressure, a few pumps and the pedal gets stiff, regardless of the steering wheel's position. If you have the wheels turned all the way to the left, pump up pressure and start the car, the pedal immediately sinks to the floor and you can't build pressure unless you straighten the wheels. Brake booster? That's the only part of the system that relies on the engine being running to operate, but I've done all of the tests in the helms manual and it passes with flying colors...and I still can't figure out why the hell it makes any f&*king difference how the wheels are oriented...

Any other ideas? Thanks, -Z

 

Maybe the brake booster is loose or something and everytime you crank the wheel it flexs the firewall and creates a leak?
