Defect SummaryKenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.
Consequence SummaryCracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.
Corrective SummaryDealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. the recall is expected to begin or before july 25, 2009. owner may contact kenworth at 1-425-828-5440.
