I have had a complete brake job because all of the lines rusted out and failed as i was driving. fortunately, i was able to use the emergency brake to stop safely. i spent rough.y $3,000 to get this repaired. now the fuel lines, fuel cooler and everything attached has rusted out to the point that it is going to be an additiona $2,500 to repair this. also, the complete under carriage and rear end has rusted to the point that i am expecting it to fail at any time. this is not only a dangerous situation, but is extremely costly to the consumer, me. when the brakes failed, i was driving on a street approaching a busy intersection. with no warning at all, the pedal went to the floor and i had no brakes. the repair facility mechanic said he has never seen a system so bad. i keep the vehicle in a garage and have washed the under carriage in the winter to keep road salt from accumulating.
