What's wrong?
The parking brake system on a 2018-2021 Autocar Xpeditor truck is designed to hold the truck stopped when the driver sets the park brake. On the right-hand drive cab configuration in this recall, the park brake valve button sits to the right of the steering wheel. That button works with a parking brake synchronization valve, which routes air pressure so the parking brake applies and releases only when commanded.
On affected trucks, the synchronization valve plumbing was assembled incorrectly during manufacturing. With the lines routed wrong, the system does not operate as designed. The parking brake can apply unexpectedly while the truck is being used, even though the driver did not press the park brake button.
There is no warning sign before failure. The recall record does not identify a light, sound, pedal change, or other symptom that gives the driver advance notice before the parking brake applies unexpectedly.
Who's affected?
Across the 2018 through 2021 scope, the parking brake is the shared component called out for every Xpeditor listed.
