What's wrong?
The brake drum on the 2026 Mack Granite Gr (4) is the heavy round surface inside the wheel-end brake assembly. In an air brake system, the brake shoes press against the drum when air pressure applies the brakes. The steer axle is the front axle that carries steering loads, so its brake hardware has to match the axle design and braking standard.
For NHTSA campaign 25V495, Mack found that the brake drum and steer axle combination do not work together as required. Mack traced the issue to validation testing that was not completed on every vehicle variation before production. With that incompatible combination in place, the front brake assembly does not meet the required air brake performance, and brake function can be lost.
There is no warning sign before failure. The truck is not expected to give the driver a noise, pedal feel, or dashboard alert tied to this issue before the brake problem shows up.
