This bulletin applies to 2009-2012 Corvette ZR1 and 2011-2012 Corvette Z06 with Z07 models, all equipped with the ceramic brake package (RPO J57).
Corvettes equipped with ceramic rotors utilize an electronic sensor to indicate the need for brake pad replacement. The end of brake pad service life is communicated to the driver on the driver information center (DIC) with the message “CHANGE BRAKE PADS.” This sensor must be transferred to the replacement pads at the time of brake service.
When transferring the brake pad wear sensor, proper orientation of the sensor must be observed. Improper installation of the sensor will result in no indication to the driver when the pads are worn. Continued operation with worn out pads may result in scoring of the ceramic rotors.
