- Manufactured:
- 10/17/2010 - 01/27/2011
- Affected:

- Defect:
- Paccar is recalling certain model year 2011-2012 kenworth t270/370, t440/t470, t800, t660, w900 and c500 vehicles manufactured between october 18, 2010, and january 28, 2011. certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, may include a flow notch in the handle portion of the housing due to an error during the casting process. a flow notch in the handle portion may reduce the effective cross section structure and cause the slack adjuster housing to fracture.
- Consequence:
- If the slack adjuster housing were to fracture, the wheel brake to which the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash.
- Correction:
- Dealers will inspect and replace the slack adjuster housing as necessary. this service will be performed free of charge. the safety recall began on march 30, 2011. owners may contact kenworth at 425-828-5440.

- Consequence:
- Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.

- Paccar will notify owners, and provide a temporary repair until bendix develops a permanent remedy. this service will be performed free of charge. the safety recall began on february 10, 2012. owner may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
