Service brakes, air: supply: check valve
- What is wrong
- On certain heavy duty trucks equipped with meritor wabco pneumatic anitlock brake system (ABS) valve packages, the assembly bolts on these valve packages were not tightened correctly.
- Risk
- Bolts torqued below specification will not reliably prevent air leakage at the affected ABS valve package interface joints once the component begins normal vehicle operation. If air leaks develop at any of the ABS valve package interface joints, brake system pressure reductions could occur during braking or normal operation with units equipped with the traction control option, potentially extending stopping distances, possibly resulting in a vehicle crash.
- Remedy
- Dealers will tighten the fasteners to the proper specification. Owner notification began february 15, 2002.
