What's wrong?
The brake S-Cam tube bracket assembly is part of the air drum brake hardware on the steer axle of 2012-2013 International Transtar and Prostar trucks. The S-Cam turns inside the brake assembly and pushes the brake shoes outward against the drum. The bracket and tube keep that cam supported and aligned so the brake applies the way the driver expects.
On included trucks, the bracket assembly on the steer axle can fracture. When that support breaks, the S-Cam tube no longer stays in its proper position. The recall summary does not identify a separate material, supplier, or installation cause, so the defect is the bracket fracture itself.
There is no warning sign before failure. A driver is not told to watch for a light, noise, pedal change, or other symptom before the bracket breaks.

What should I do if my 2012-2013 International Transtar or Prostar is on this recall?
