Summary
Proterra is recalling certain 2016-2017 Proterra Catalyst 40 transit buses equipped with axles with 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.
Consequence
Breakage of the guide pin can cause loss of braking ability or loss of tire pressure, increasing the risk of a crash.
Remedy
Proterra will notify owners and have them replace the calipers on the affected axles, free of charge. Owners may contact Proterra customer service at 1-864-438-0000.
