[Biturbos4] brake problem

Not much help, but food for thought ... seems significant to me that something must be activating the ABS other than signals from the wheel speed sensors.  I'd guess something nasty going on inside the ABS unit itself, which doubles as a master cylinder of sorts, which is a traditional problem area with a soft pedal.  Forgive me if I'm emphasizing the obvious.  Just thinking with the keyboard.  Probably worth trying to check for ABS Diagnostic Trouble Codes.  Good luck.
