FCCC XCM 2021 Service Brakes Recall: Loose Bolt Risk
DTNA recalls 2021 Western Star 4700/5700 and Freightliner models with potentially loose brake caliper bolts, risking reduced braking effectiveness and crash risk. Owners must contact DTNA for free repair.
Use caution until it’s fixed
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.
