Reported risk: Issue:
Certain trucks may have been built without a quick release valve for the rear brakes. As a result, the rear brakes may release too slowly when the brake pedal is released. Canadian regulations require air brakes to release within a certain time.
Safety Risk:
Rear brakes that release too slowly could increase the risk of a crash.
Corrective Actions:
Mack will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, install the quick release valves.
Verify each fact at the issuing agency before acting. Recall scope, affected lots, and remediation instructions may be updated by the agency after our last sync.
