Defect
Paccar is recalling 86 my 2009 kenworth t660, t800, w900, and peterbilt 386, 365, and 388 trucks equipped with bendix front air disc brakes. The size 14 service chamber of certain front air disc brakes may have been contaminated with grease between the piston head/plate and the diaphragm. When braking pressure is applied, the grease may allow the piston head/plate to slip off center and catch on the reducing ring of the size 14 service chamber.
Safety risk
The catching of the piston head/plate on the reducing ring may lock up the corresponding front air disc brake which may impact the operator's ability to steer or control the vehicle.

Dealers will replace both front air disc brakes size 14 service chambers free of charge. The recall began on august 27, 2008. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
