Certain trucks equipped with Bendix SR-7 spring brake modulating valve may experience an internal air leak if the check valve fails to seat. This may cause a delay in the application of the parking spring brakes leading to an unintended vehicle rollaway. Correction: Dealers will replace the Bendix SR-7 valve and the Parker single check valve.
