2008 FREIGHTLINER MT-45 Recall

Campaign:

07V302000 on 07/15/2007

Component:

Service brakes, air:supply:check valve

Manufactured:

06/30/2002 - 07/02/2007

Affected:

75,000

Defect:

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.

Correction:

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.
