I have a 2003 Ford Expedition, 4 wheel drive with a 4.6Liter. Need to replace the Master cylinder, pedal slowly sinks to floor under continuous pressure, all other braking is fine. Parts store lists the Master Cylinder with and with/out (IVD). I have searched the manual for either IVD or Advancetrac Stability Assist and have found nothing. How do I tell if this vehicle has IVD? Appreciate any assistance.
