Jaguar Australia—Certain Jaguar XJ 2003 and certain 2004 vehicles—Under Floor Brake Pipe Corrosion
What are the defects?
A concern has been identified with corrosion to brake pipes at the junction between the twin under floor pipes and the rear cross member pipes fitted to 2003 and certain 2004 MJ XJ vehicles.
A review of vehicle build shows that a touch condition can exist between the under floor brake pipes and the Noise Vibration Harshness (NVH) pad at the rear of the under floor under tray. Where a touch condition exists, water and dirt can collect and be held in contact with the pipes and their unions reducing the corrosion life of the pipes accordingly.
In these cases the corrosion can lead to loss of the mechanical integrity of one or both pipes. This can result in extended brake pedal travel combined with reduced braking performance in the corresponding circuit, and simultaneous display of the 'fluid level low' warning light. In the event of both pipes losing integrity at the same time, complete loss of service brakes will occur.
