Affects Blue Bird TX4 School Bus, Vision School Bus · 2022 — about 8 vehicles.
The hazard
Issue: On a small number of school buses, a check valve within the air brake system may not have been assembled correctly. As a result, there could be an air pressure leak if there is a secondary brake circuit failure. This could cause the parking brakes to apply suddenly. Note: This recall only affects school buses built with a Bendix air brake system. Safety Risk: A parking brake that self-applies while driving could increase the risk of a crash. Corrective Actions: Blue Bird will notify owners by mail and instruct you to take your bus to a dealer to inspect, and if necessary, replace the SC-3 check valve.
