On a small number of trucks equipped with air disc brakes and a certain steering arm configuration, a single brake caliper mounting bolt on the left side of the steering axle may not be properly tightened.
Safety Risk
Reduced braking could cause an increase in stopping distance and create the risk of a crash.
Corrective Actions
Daimler Trucks North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to inspect and replace the brake caliper bolts, as necessary.
