Hazard
Blue Bird Body Company (Blue Bird) is recalling certain 2015-2020 Vision and All American school buses equipped with Bendix ADB22X air brakes. The driver side rear brakes may drag.

A dragging brake may cause damage to the brake components, which may activate the ABS warning light. The warning light may cause the driver to immediately stop the vehicle and transfer occupants. Additionally, the high temperatures at the wheel end can increase the risk of a fire. Either condition increases the risk of injury.
Remedy
Blue Bird will notify owners, and dealers will install a new caliper with an updated clearance adjustment mechanism, free of charge. Blue Bird issued owners interim notification on July 18, 2019. The recall began August 28, 2019. Owners may contact Blue Bird customer service at 1-478-822-2242. Blue Bird's number for this recall is R19AA - SB.
