Mack Trucks, is recalling 5,203 model year 2013-2014 CHU, CXU, GU, MRU, and LEU trucks manufactured July 16, 2012, through March 18 of this year that are equipped with drum brakes.

A National Highway Traffic Safety Administration bulletin says the clevis pin for the brake slack adjuster 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. It says 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.

Mack will notify owners and dealers will inspect the brake slack adjusters and install the brake hardware, as necessary, free of charge. The recall is expected to begin on, or before, June 17. Owners may contact Mack Trucks at 1-800-528-6586. The recall campaign number is SC0370. Affected owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or go to
