The 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.
The 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.
