Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Plain-English summary

Mack Trucks, Inc. is recalling certain model year 2013-2014 CHU, CXU, GU, MRU, and LEU trucks manufactured between July 16, 2012, and March 18, 2013. The recall affects 5,203 vehicles equipped with drum brakes. The defect involves the clevis pin for the brake slack adjuster, which may be missing a cotter pin. If the cotter pin is not installed, the clevis pin may loosen and fall out, causing a loss of brake function on the affected wheel.

A loss of brake function at one wheel will lead to increased stopping distances and pulling to the left or right when braking, which may increase the risk of a crash. No specific injuries or fatalities are reported in the source text.

Mack Trucks will notify owners, and dealers will inspect the brake slack adjusters and install the necessary brake hardware free of charge. An interim notice was mailed to owners on June 20, 2013, and a second notice was mailed on September 30, 2013. Owners may contact Mack Trucks at 1-800-528-6586 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
