NHTSA (USA)High Risk
At a glance
What can fail
The S-cam tubes on the air brake axle assemblies lack lubrication, allowing corrosion to develop over time and potentially restrict brake release at the wheels.
What the fix does
Dealers will lubricate the S-cam tubes and inspect them for free movement at all four wheel locations at no cost.
