SERVICE BRAKES, AIR
- The defect
- 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.
- What it can cause
- Inoperative rear axle brakes can increase the distance required to stop, increasing the risk of a crash.
- What the dealer does
- 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.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 124 vehicles this is a small campaign: 67% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published are as large or larger. The middle campaign on file covers 472. It covers one model year, 2021, and the defect was reported to NHTSA in 2021, at or before the oldest model year it covers — as current as a recall gets.
Mack vehicles have been recalled over the service brakes, air 27 times before this, most recently in February 2019 as 19V107000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 9 other recalls published here, the newest being: 25V666000 (seat belts), 24V792000 (service brakes, hydraulic), 24V773000 (tires), 23V600000 (exterior lighting).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Mack Trucks, Inc. with NHTSA on July 27, 2021 as campaign 21V573000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
