According to Mack Trucks, Inc., the affected actuators may have an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of the parking brake section of the actuator. And, if the diaphragm is not completely attached, there may be internal leakage from the service section, potentially trapping air pressure in the parking brake section. The air pressure, if not vented, may prevent full release of the actuator unit, induce brake drag, and result in overheated wheelend service brakes. Mack Trucks, Inc. admits that this these circumstances increase the risk of a fire.
According to the National Highway Traffic and Safety Administration ("NHTSA"), Mack
Trucks, Inc. will notify vehicle owners directly, and its authorized dealers will inspect the brake actuator and replace, as necessary, free of charge. The recall is expected to begin February 27, 2015.
