On certain buses, the emergency brake valve may not have been installed correctly. As a result, the valve could become loose or disconnect and cause an air leak. If this happens, the parking brake could apply suddenly while driving without the brake lights turning on.
A parking brake that self-applies suddenly while driving without the brake lights turning on could cause a person not to recognize that the vehicle is braking. This could increase the risk of a crash.
Nova Bus will notify owners by mail and provide you with instructions for how to inspect and reassemble the air-line connections correctly.
