Service brakes, air: supply: check valve
- What is wrong
- 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.
- Risk
- 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.

Tl* the contact owns a 2005 freightliner business class m2. While driving approximately 40 MPH, the front driver side tire and wheel assembly detached from the vehicle and rolled across the road crashing into the side of a brick house causing moderate damage. There was no personal injury. A police report was filed. The vehicle was towed to an authorized dealer. The technician informed that the failure was contributed to the front axle wheel. The vehicle was repaired under the federal safety agency campaign id number 08v137000 (power train:axle assembly). The identical failure reocurred on a separate occasion after the remedy repair had been performed on the vehicle. The vehicle was repaired at the dealer. The contact expressed significant concern of the safety hazard. The failure mileage was unknown. Updated 01/26/11*lj updated 04/18/11
Tl*the contact owns a 2005 freightliner business class m2. While driving approximately 50 MPH, the contact felt the rear brakes dragging. There was no rear braking. The contact managed to stop the vehicle with the front brakes. He took the vehicle to the service dealer and they stated that the ABS snensor detached from the metal holder, which overheated and melted the ABS sensor. The failure and current mileages were 32,300. Updated 06/03/10*bf updated 06/07/10
High pressure fuel lines broke, causing a breakdown, tow and repair. Loss of fuel also. Lines were replaced at authorized dealer with what was available. This breakdown not including fuel loss resulted in a lost day and $700 costs. 3 months later, we received recall notice to replace the lines again. The notice says we could qualify for reimbursement, but when I called detroit diesel, they said no. Seems that defective lines were the problem all along, regardless of the time frame.
Parking air brake valve has broken loose from inner (plastic) dash mount rendering it very difficult to engage or disengage the brake. This could cause death or injury if the parking brake cannot be engaged. I have found this to be a common complaint with this vehicle as well as sterling medium duty trucks per the internet. Replacement inner dash plus labor is very expensive and provides no guaranty it won't break again. This is poor design using inadequate material in a high stress area. (VIN entry block will not accept my VIN even though it is correct).
Dt*: the contact stated while driving 65mph, the fuel line assembly burst without warning and began to spray diesel fuel onto the vehicle and the highway. The vehicle was parked on the side of the highway without further incident. Upon inspection of the vehicle, the contact determined the fuel lines were fractured and needed to be replaced. A the federal safety agency recall, #05v469000 remedy repair to the engine by emc recalibration and replacement of the fuel lift pump was performed which pertained to the fuel system. However, the recall did not remedy the problem. The dealership would not offer an additional repair without charge under the recall. The manufacturer was alerted.
