What's wrong
Mack Trucks, Inc. (Mack) is recalling certain 2021 Granite, LR, and TerraPro vehicles. The rear drive axle may have the incorrect type of brake cam installed, which could result in inoperative rear axle brakes.
The risk
Inoperative rear axle brakes can increase the distance required to stop, increasing the risk of a crash.
The fix
Dealers will inspect the brake cams, and incorrect brake cams will be replaced, along with brake shoes, hardware, and wheel seals, as necessary, free of charge. Owner notification letters were mailed on August 10, 2021. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0427.
