2013 MACK GRANITE (GU) Recalls (9)

Campaign:
12V037000 on 02/02/2012
Component:
Service brakes, air:supply:check valve
Manufactured:
12/01/2010 - 01/17/2012
Affected:
2
Defect:
Mack is recalling certain model year 2012-2013 gu, manufactured from december 2, 2010, through january 18, 2012, and equipped with bendix atr-6 traction relay valves. in extremely cold conditions, these bendix relay valves may potentially develop internal leakage. internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.
Consequence:
Inadvertent brake application can cause the brakes to overheat and lead to a fire. inadvertent brake application can cause the wheels to lock-up leading the driver to lose control of the vehicle, increasing the risk of a crash.
Correction:
Mack will notify owners, and provide a temporary repair until bendix develops a permanent remedy. this service will be performed free of charge. owners may contact mack trucks at 1-800-866-1177.
Notes:
Mack trucks' recall number is sc0363.owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to <a href=http://www.safercar.gov>http://www.safercar.gov</a> .

Mack trucks, inc. is recalling certain model year 2013-2014 chu, cxu, gu, mru, and leu trucks manufactured july 16, 2012, through march 18, 2013 and equipped with drum brakes. the clevis pin for the brake slack adjuster may be missing a cotter pin. if the cotter pin is not installed, the clevis pin may loosen and fall out causing a loss of brake function on the affected wheel.
Consequence:
A loss of brake function at one wheel will lead to increased stopping distances and pulling to the left or right when braking, which may increase the risk of a crash.
Correction:
Mack trucks, inc. will notify owners, and dealers will inspect the brake slack adjusters and install the brake hardware, as necessary, free of charge. an interim was mailed to owners on june 20, 2013. a second notice was mailed to owners on september 30, 2013. owners may contact mack trucks at 1-800-528-6586. mack trucks' recall campaign number is sc0370.
