NHTSA campaign 18V394000
Hazard
New Flyer of America, Inc. (New Flyer) is recalling certain 2014-2016 New Flyer XT60, 2014-2017 New Flyer XN60 and XD60, and 2015-2017 New Flyer XDE60 urban transit buses equipped with ZF Axles that have radial air disk brakes. Surface roughness of a guide pin in the radial brake calipers may cause the brake carriage guide pin support bolt to break. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Consequence
Breakage of the guide pin can cause a reduction of braking ability and an increase in stopping distances, or a loss of tire pressure, increasing the risk of a crash.
Remedy
New Flyer will notify owners, and dealers will install a bushing kit and reinstall the brake calipers, free of charge. The recall began June 29, 2018. Owners may contact New Flyer customer service at 1-204-224-6706. New Flyer's number for this recall is R18-010.
