Defect: Caterpillar Inc. (Caterpillar) is recalling certain model year 2012-2013 CT660 trucks manufactured August 2011 through August 2012, and equipped with feature code 0504501, 0504504, or 04EWM Reduced Stopping Distance (RSD) brake linings and with or without feature code 04WCS Greased For Life front air S-cam brakes.
