Paccar trailers recalled due to brake failure hazard

Posted on

Paccar Incorporated, at the request of the United States National Highway Traffic Safety Administration, has issued a voluntary recall for seven various designs of trailers from model year 2013. These trailers, all Kenworth T680 or Peterbilt 579 vehicles, exceed the requirements for brake timing test results mandated by the federal safety standards regulating air brake systems for trailer circuits equipped with 15 foot coiled trailer lines. The braking distances may be unexpectedly longer than anticipated because of this possible violation of Federal Motor Vehicle Safety Standard number 121 regulating the “Air Brake Systems” on these vehicles. The issue is due to a possible defect in the service brake air supply hose lines pipes or fittings. This delayed stopping may increase the likelihood the trailer will become involved in a collisions possibly causing severe injury or death. Paccar plans to begin informing consumers of this potential safety issue in July of 2012. Owners of affected Kenworth T680 and Peterbilt 579 trailers can return them to their original place of purchase for a corrective repair. A relay valve remedying the brake time delay issue will be installed on recalled vehicles at no cost to their owners.  Consumers seeking more information on this recall may contact either Kenworth (reference recall number 12KWB) or Peterbilt (reference recall number 0512-A), or call the National Highway Traffic Safety Administration’s Vehicle Safety Hotline and reference campaign identification number 12V214000.
