The defect
Blue Bird Body Company (Blue Bird) is recalling certain 2022 Vision school buses equipped with Ford 7.3L engines. The retaining clamp used to secure the hydraulic brake line near the engine may not have been installed, which could cause the brake line to rub which could cause a brake fluid leak and result in a loss of brake function.
The risk
Loss of braking ability increases the risk of a crash.
