Freightliner Custom Chassis (Fccc) B2 School Bus Chassis: Brakes
Affects Freightliner Custom Chassis (Fccc) B2 School Bus Chassis · 2004–2006 — about 13 vehicles.
The hazard
On certain vehicles, inconsistent actuation of the park brake relay valve may cause delayed park brake application. At higher vehicle loads, a bus may roll if the driver releases the service brakes before the parking brakes fully apply. A moving bus may cause a vehicle crash or injure passengers entering or leaving the bus. Correction: Dealers will install a check valve to reduce the park brake application time by adding an exhaust path around the relay valve.
