What's wrong: Severe corrosion due to road salt at the joint of the stamped steel center section and the cast outer section can cause the sections to separate.
Why it matters: Separation of the rotor sections can cause loss ofbraking ability in the affected wheel. This could result in increased stoppingdistance and/or loss of vehicle control and an accident.
The fix: Replace the front brake rotors with new rotors with a corrosion protection coating. However, if replacement of brake linings are necessary, it will be done at owner's expense since brake linings are normal maintenance items.
