DEFECT #1 - SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
Posted on: 2007-07-16
Description
Certain freightliner school bus chassis, heavy trucks, and thomas built school buses manufactured between july 2002 and july 3, 2007, equipped with bendix sr-7 spring brake control valves. The parker scv brass 90 degree single check valves (scv) which attach to the supply port of a bendix sr-7 spring brake modulating valve can break apart. Pieces of the parker scv can become lodged inside the sr-7 spring brake modulating valve, potentially causing either leakage out of the sr-7 valve or preventing air from properly exhausting from the sr-7 valve. Also, due to a manufacturing defect in the internal rubber check valve inside the sr-7 spring brake modulating valves, the valves can become deformed and not seat properly.
Consequence
These conditions could either result in leakage and cause a delay in the application of the spring brake without warning or possibly lead to unintended vehicle rollaway or brake drag which could result in a vehicle crash, personal injury, or death.
Corrective Action
Freightliner will notify owners and repair the vehicles free of charge. The recall began on january 11, 2008 to freightliner, sterling, and freightliner custom chassis owners; to thomas built bus owners on february 1, 2008. Owners can contact freightliner at 1-800-547-0712.
