    In plain language

    This recall affects certain 2013 and 2014 Mack CHU, CXU, GU, LEU, and MRU trucks in Canada. The cotter pin that holds the brake slack adjuster's clevis pin may be missing. This could cause the clevis pin to loosen and fall out, leading to a loss of brake function at the affected wheel. This could cause the vehicle to pull to one side under braking or increase stopping distance, which could result in a crash.
