The problem
Vehicle description: heavy duty trucks equipped with meritor air brake automatic slack adjusters. Some of the automatic slack adjusters had insufficient torque applied to the guide pawl cap screw.
The risk
Without sufficient torque on the guide pawl cap screw, the brakes could gradually lose adjustment, increasing the vehicle stopping distance.
The fix
Dealers will check the torque on the automatic slack adjuster guide pawl. If there is no torque, the brakes will be adjusted and the guide pawl will be tightened to 15-20 ft. Lbs.
