PREVOST recall on H3-41 COACHH3-45 COACH, and X3-45 COACH models

On certain motor coaches, a check valve inside the spring brake modulating valve may not properly seat causing internal air leakage. The leakage can result in delayed application of the spring brakes to park the vehicle after the operator pulls the dash valve button. The delayed parking brake application can occur without warning leading to unintended vehicle rollaway, increasing the risk of a crash. Correction: Dealers will inspect and, if required, replace the brake valve.
