Brakes - Rear Brake Squeal On Application/Turns
TSB 12-1-101/11/12
BRAKE SOUEAK/SOUEAL - REAR BRAKES - BUILT 7/19/2011 THROUGH 12/1/2011
FORD:
2012 Mustang
ISSUE
Some 2012 Mustangs built 7/19/2011 through 12/1/2011 may exhibit a squeak/squeal from the rear brakes during brake application and/or when making turns. The squeak/squeal sounds like a metal-on-metal noise (similar to a brake wear indicator noise). This concern may be due to a rear brake anti-rattle spring clip contacting the brake rotor when applying the brakes due to a broken locating tab on the anti-rattle spring clip. This may allow the anti-rattle spring clip to lightly contact the rotor causing the noise.
ACTION
Follow the Service Procedure steps to correct the condition.
