Affected Units:: 1,350
Vehicle description: heavy duty trucks equipped with hydraulic brakes and a durapark park brake system manufactured by arvinmeritor. Air is entering the hydraulic rear brake cylinders through an unknown path and the rear self-adjusting brakes may not be operating properly.
Dealers will remove and replace the abs ecu and inspect the brake pedal for proper travel. If excessive travel is detected, the brake system will be bled and rear brakes adjusted. As an interim measure, freightliner will notify all owners to have their vehicles inspected to assure proper function of the brake system. This will include adjusting and bleeding the brakes. Also, owners will be instructed that on a regular basis they should do several hard brake applications while stopped. This will exercise the self-adjusting system and if they observe a low or spongy brake pedal they will be instructed to take their vehicle in for additional service. Owner notification began March 21, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact freightliner at 1-800-547-0712.
Also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
