NHTSA Campaign Id 11V167000; Date: Mar. 14, 2011
If the slack adjuster housing were to break, the wheel brake to which the slack adjuster is attached would no longer function, reducing braking capacity and, in some cases, causing the vehicle to pull to one side. Reduced braking performance and/or loss of steering control increases the risk of a crash.
Recalled Vehicles:2011 International Durastar; 2012 International Durastar; 2011 International Workstar; 2012 International Workstar

Recall Summary:Navistar is recall certain model year 2011 and 2012 International durastar and workstar commercial trucks manufactured from October 19, 2010, and February 3, 2011, equipped with gunite automatic slack adjusters. Due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
How to Fix:Navistar will notify owners and dealers will replace the subject slack adjusters free of charge. The safety recall is expected to begin on or about April 1, 2011. Owners may contact navistar at 1-800-448-7825.
