Potential Number of Units Affected: 331

Manufacturer: Mack Trucks, Inc.


SUMMARY:
Mack Trucks, Inc. is recalling certain model year 2011-2013 CXU trucks manufactured November 23, 2010, through March 19, 2012. These vehicles are equipped with an MGM Type 24 J-series piston parking brake chamber. In the affected axles, the brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.
CONSEQUENCE:
Overheated brake components could result in a fire.
REMEDY:
Mack Trucks will notify owners and the brake chambers will be replaced as needed, free of charge. The safety recall is expected to begin on, or before, June 17, 2013. Owners may contact Mack at 1-336-393-2000. Mack Truck's campaign recall number is SC0369.
