Certain school buses do not comply with the requirements of CMVSS 121 - Brake Systems. The rear brake valve module was incorrectly fitted with a standard 90-degree elbow where a 90-degree check valve should have been used. As a result, the rear brake system does not meet the CMVSS bleed down test. In addition, in the event of a catastrophic line failure, the emergency brakes will apply without warning. Correction: Dealers will affect repairs.
