Defect
BYD Coach & Bus (BYD) is recalling certain 2016-2017 K11M hybrid electric 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.
Safety risk
Breakage of the guide pin can cause a loss of braking ability or a loss of tire pressure, increasing the risk of a crash.
Remedy
BYD will notify owners, and dealers will install a bushing kit and reinstall the brake calipers, free of charge. The recall began October 11, 2018. Owners may contact BYD customer service at 1-661-940-3250.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
