Vette Pad Sensor Caution

2011-2012 Corvette models equipped with the Z06 with Z07 and 2009-2012 Corvette ZR1 models equipped with J57 ceramic brake packages feature ceramic brake rotors that use an electronic sensor to indicate the need for brake pad replacement. The end of service life is communicated to the driver on the DIC (driver information center) with the message “CHANGE BRAKE PADS.”

This sensor must be transferred to the replacement brake pads.

When transferring the brake pad wear sensor, proper orientation of the sensor must be observed. Improper installation will result in no indication to the driver when the pads are worn. Continued operation with worn pads may result in scoring of the ceramic rotors.

This shows the proper orientation of the wear sensor. 1) Electronic brake pad wear sensor; 2) Brake pad friction material; 3) Brake pad backing plate; 4) Steel anti-rattle plate. Notice that the sensor inserts through the opening in the pad and backing plate. The thicker side of the sensor is aligned with the brake pad friction material. The sensor wire is looped firmly over the caliper and is positioned well away from rotating parts.
