Transport Canada Recall - 2017508 - NAVISTAR

On certain school buses, the air brake drop hose fittings to the service brake chambers on the steer axle wheel ends may not be oriented correctly. When the steer wheels are turned to their fullest travel and with full suspension articulation, it may result in the hose making contact with the tire and cause damage to the hose and cause an air leak. An inoperative brake at the affected wheel end could result in a pull condition during brake application or an unexpected increase in stopping distance, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will reorient the drop hose fittings and replace any drop hose or wheel speed sensor harness found with abrasion damage.
