Caterpillar CT660: Service brakes

Affects Caterpillar CT660 · 2012–2013 — about 181 vehicles.

The hazard

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.

What to do

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.
