Issue: On certain trucks, the inversion valve in the air brake system may not work properly. As a result, there could be a delay before the parking brake applies. If this happens, the vehicle could move unexpectedly. This issue also causes the vehicle not to meet the requirements of the Canadian regulations. Safety Risk: A delay before the parking brake applies could result in unintended vehicle movement, and create the risk of an injury or a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify the owners by mail and advise you to take your truck to a DTNA authorized service facility to inspect and, if necessary, replace the inversion valve.
