SERVICE BRAKES, AIR:DISC:CHAMBER

Issued by Mack Trucks, Inc. · Reported Aug 17, 2015 · 79 vehicles affected

What's wrong

Mack Trucks, Inc. (Mack) is recalling certain model year 2013-2015 Pinnacle (CXU) trucks manufactured from October 3, 2012, through February 18, 2014 and equipped with Meritor air disc brakes. In the affected vehicles, the brake chambers may have been incorrectly mounted resulting in internal contamination of the air brake calipers.

Consequence

Contamination of the calipers may cause a loss of brakes on one wheel, lengthening the distance required to stop the vehicle, increasing the risk of a crash.

Remedy

Mack will notify owners, and dealers will inspect the disc brake caliper and brake chamber to determine if the washers are located in the correct position. If the washers are in the correct position, no further action is required. If the washers are not located in the correct position, replacement of the disc brake caliper and brake chamber will be performed and the addition of two washers per brake assembly will be installed, free of charge. The recall began on September 30, 2015. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0392.
