What's wrong?
The drive axle brake drums on the 2026 Mack Granite Gr (4) are part of the air brake system at the rear axle. When the brakes apply, the shoes press against the inside of each drum to slow the truck, so the drum rating has to match the weight the rear axle is allowed to carry.
On affected trucks, Mack says the installed drive axle brake drums should have changed the rear axle rating from 29000 lbs to 27000 lbs. The door jamb label did not show that lower rating. That leaves the truck labeled for more rear axle load than the installed brake drum setup supports.
An owner or driver will not feel this problem in normal brake pedal operation. There is no warning sign before failure, because the issue is the match between the installed brake drums and the load rating shown on the label.
