The hazard
On certain vehicles, the required check valve may not have been installed in one of the ports of the spring brake modulation valve. In the event of a rapid loss of air pressure in the secondary system, the missing check valve could cause a similar rapid loss of pressure in the primary system, which may lead to a sudden application of the parking brakes. This could increase the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks North America authorized service facilities will inspect and the check valve will be installed if needed.
