Recalls for 2013 Caterpillar Ct660

DEFECT #1 - SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

Posted on: 2012-02-13
Description
Caterpillar is recalling certain model year 2012-2013 ct660 commercial trucks, manufactured from december 2, 2010, through january 26, 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
Unexpected continuous brake application can cause the brakes to overheat and lead to a fire.  Unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash.  Also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.

Corrective Action
Caterpillar will notify owners, and dealers will repair the vehicles free of charge.  Owners may contact caterpillar at 309-675-5658.  

Notes
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 http://www.safercar.gov .

DEFECT #2 - SERVICE BRAKES

Posted on: 2014-02-26
Description
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.  In the affected vehicles, the brake s-cam brackets may fracture.  

Consequence
S-cam bracket fractures may result in an inoperative brake on the affected wheel.  This will cause the vehicle to pull to one side unexpectedly during braking and/or increase the stopping distance.  Either result may increase the risk of a crash.  

Corrective Action
Caterpillar will notify owners, and dealers will replace the s-cam brake assemblies with a brake assembly with cast spiders and s-cam tube bracket assemblies with reinforced gussets, free of charge.  The recall began on april 11, 2014.  Owners may contact caterpillar at 1-888-614-4328.
