Component: Air Brake
Manufactured by: International Truck And Engine
Affected Units:: 944
Vehicle description: heavy duty trucks. There is interference between the air brake s-cam and the end of one of the knuckle studs. As the brake shoe lining wears, the s-cam rotation may be limited by the interfering knuckle stud. If the s-cam can not rotate through its full range of motion, the braking force can not be fully transmitted from the brake shoe linings to the brake drums.
Dealers will shorten the interfering knuckle stud to eliminate the clearance problem.
