What NHTSA recorded

On certain heavy duty class 8 trucks equipped with air suspension proprietary axles and adjustable lengh torque rods, an interference between the adjustable torque rod and the brake chamber on the left side of the chassis may exist. The spring brake chamber clamp ring could possibly be distorted over time resulting in loss of air, which could lead to the spring brake at the chamber being inadvertently applied.

Possible consequence

Braking capability would be diminished, increasing the risk of a crash.

Remedy

Dealers will repair and replace the adjustable torque rod, with a fixed length torque rod, inspect and repair the brake chamber free of charge. The recall began on may 3, 2005. Owners may contact mack trucks at 610-709-2131.
