2001 Mack CV recall: brakes
⚠️ What's wrong
On certain trucks equipped with meritor wabco pneumatic anitlock brake system (ABS) valve packages, the assembly bolts on these valve packages were not tightened correctly.
💥 The 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.
🔧 The fix
Dealers will tighten the fasteners to the proper specification. Owner notification began june 13, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mack at 1610-709-3337..
