NOVA BUS issued a recall on multiple vehicle models

Certain transit buses equipped with Arvin Meritor "W-Series" air-actuated brake cam rollers. These rollers were installed as original equipment and also sold as replacement parts. The affected brake rollers may fracture if subjected to high application loadings. If one or more of the affected brake rollers fracture, proper brake application could be compromised, possibly resulting in a vehicle crash. Correction: Dealers will inspect brake rollers and replace them if necessary.
