Brake Pad Wear Sensor
Corvette models equipped with RPO J57 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 brake pads at the time of brake service.
Warning
When transferring the brake pad wear sensor, proper orientation of the sensor MUST be observed. Improper installation of the electronic sensor will result in no indication to the driver when the brake pads are worn.
Continued operation of the vehicle with worn out pads may result in scoring of the brake rotors.
Brake Pad Wear Sensor Installation
Figure 1
Figure 1 shows the proper orientation of the electronic brake pad wear sensor. The sensor must be installed to the brake pad with the thicker side of the sensor aligned with the brake pad friction material as shown.
Figure 2
Figure 2 illustrates a slightly different view of the electronic brake pad wear sensor properly installed. Note that the sensor wire is looped firmly over the caliper and is positioned well away from rotating parts. Please confirm proper installation of the electronic brake pad wear sensors whenever the brake pads are removed or serviced for any reason.
