What's wrong?
The rear brake chambers on 2013-2016 Autocar Xpeditor trucks convert air pressure into mechanical force at the rear brakes. On trucks with auxiliary axles, the chamber size has to match the brake setup so the brakes apply with the right force. The S-cam tube is part of that brake assembly; it helps rotate the cam that spreads the brake shoes against the drum.
On affected trucks, the installed 36/36 rear brake chambers were too aggressive for this configuration. That incorrect chamber type caused over-braking, which created excessive vibration through the brake assembly. Over time, that vibration loosened the S-cam tube bolts. Once those bolts loosen, the rear brakes can engage unexpectedly instead of responding only to the driver's brake input.
There is no warning sign before failure. An owner or driver should not count on noise, pedal feel, or a dashboard alert to reveal that the S-cam tube bolts have loosened.
