SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER

Issued by Daimler Trucks North America, LLC · Reported Jan 20, 2021 · 133 vehicles affected

What's wrong

Daimler Trucks North America, LLC (DTNA) is recalling 2021 Western Star 4700 and 5700, Freightliner Business Class M2, Cascadia, and Custom Chassis XC Chassis vehicles manufactured with a certain steering arm configuration with air disc brakes identified by the axle assembly supplier. On certain vehicles, one of the six brake caliper mounting bolts on the driver side steer axle may have been incorrectly tightened.

Consequence

The loose bolt could result in the other caliper bolts to loosen. Insufficiently tightened bolts may not provide adequate clamping force between the brake caliper and brake anchor plate, resulting in reduced brake effectiveness, increasing the risk of a crash.

Remedy

DTNA will notify owners, and dealers will inspect and repair as necessary, free of charge. The recall began March 17, 2021. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-873.
