Or it could be an XB Coupe related brake problem.
I think I remember reading it somewhere that the front brakes are prone to locking up as this picture shows.
Coincidence or braking fault...you be the judge.
the 'engine problem' happened about 10 years ago ( the XA isn't my first coupe by a long shot ! ) I couldn't trace what the problem was but it disappeared shortly after the photos were taken ... I never did find out why it happened :s6: :s6: :s6: :s6:
