Defect
Daimler Trucks North America, LLC (DTNA) is recalling certain 2021 Thomas Built Buses Saf-T-Liner HDX and EFX school buses. On certain vehicles, one of the six brake caliper mounting bolts on the driver side steer axle may have been incorrectly tightened.
Safety risk
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.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
