| Defect Summary | 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 Summary | 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 Summary | 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. | |||||||||||||||

| Odi opened a preliminary evaluation(pe11-007) based on one fleet report that it had experienced multiple wheel-end fires.the fleet believed the fires were due to a power spring fracturing and puncturing a brake chamber diaphragm resulting in a loss of compressed air to the brakes.the loss of air was then believed to cause the brakes to drag and overheat.brake chambers have a limited service life and are subject to wear out and the effects of corrosion.however, the failures identified by the fleet occurred much earlier in their life than expected and may not have exhibited discernible failure symptoms or provided adequate warning to the operator.a vehicle driver suffered smoke inhalation during one of the fires suspected to have been caused by the alleged dragging brakes.another injury was sustained by a mechanic when he attempted to remove the brake chamber with a broken power spring.the brake chamber sprung from its mounting bracket as it was loosened and struck the mechanic in the face, causing multiple lacerations.odi has initiated testing at the vehicle research and test center (vrtc) to determine the cause of the spring failures and the effect they may have on the wheel-end brakes.odi is also looking to better understand any warning signs that may precede a power spring failure.odi has upgraded this investigation to an engineering analysis to further evaluate the cause of the wheel fires and assess the scope, frequency, and safety consequences of the alleged defect. | ||||||
