Summary: Rear brake relay valve control line was connected to the secondary double check valve, rather than the primary one. Consequence of defect: these trucks have a two axle brake system each on separate systems to avoid total loss of brakes. However with the misconnected lines and if a rupture or leak occurs in the control line, the front and rear axle brakes will fail.
Remedy: Properly connect control line to the primary double check valve. Recheck for proper operation of front brakes.
Notes: System: air brakes plumbing.vehicle description: heavy duty low cab forward trucks. Model FLL6384.

Has your Freightliner been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Freightliner dealer can also check your VIN. Recall repairs are free.
