The hazard
On certain vehicles, the double check valve disc incorporated into the brake manifold dash valve can become brittle over time and crack. If this condition exists and there is a single point failure in either the primary or secondary air system, loss of all service braking could result without warning with the potential for a vehicle crash. Correction: Manifold dash valve will be replaced.
