2011–2012 Kenworth T440 recall: brakes
⚠️ What's wrong
Paccar is recalling certain model year 2011-2012 kenworth T440 tractors manufactured between october 18, 2010, and february 9, 2011 for failing to comply with federal motor vehicle safety standard no. 121, "air brake systems." the quick release air valve required in the full truck service brake air line gladhand connection may not have been installed. The omission of the quick release air valve may allow the full truck service brake air line gladhand release timing to exceed the threshold of 0.75 seconds by 1/10TH of a second, thereby failing to comply with the with the requirements of the safety standard.
💥 The risk
The service brake of a towed vehicle or trailer may have a delayed release, increasing the risk of a crash.
🔧 The fix
Kenworth dealers will install the quick release air valve in the full truck service brake air line with gladhand connection. All of the vehicles have been repaired, therefore, an owner notification letter will not be issued for this campaign. The recall began on june 23, 2011. Owners may contact paccar at 1-425-468-7400.
