- Summary
- 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.
- Consequence
- Without sufficient torque on the guide pawl cap screw, the brakes could gradually lose adjustment, increasing the vehicle stopping distance.
- Remedy
- 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.

Has your Kenworth been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Kenworth dealer can also check your VIN. Recall repairs are free.
