10-36 Vehicle Care Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes. Brake linings should always be replaced as complete axle sets. Brake Rotor Wear ZR1 models have, and Z06 and Grand Sport models may have, ceramic brake rotors. Rotors should be visually inspected whenever the brake pads are replaced. Rotors also need to be weighed before brake pads are replaced to confirm that the rotor mass is greater than the wear‐out mass printed on the rotor. The rotor can be reused if the weight of the rotor is above the mass limit. Rotor inspection and weighing methods can be found in the service manual. See Service Publications Ordering Information on page 13‑18. Brake Rotor Protector { WARNING Ceramic rotors will be very hot after operation and touching them may cause burns. Be sure brake system is completely cool prior to installation of protector, or coming in contact with them. Notice: Rotors may be chipped if hard contact is made with the wheel during wheel installation or removal. Always use the rotor protectors. Be sure to carefully follow wheel removal and installation instructions. The ZR1, Z06, and Grand Sport models also have an electronic brake pad wear sensor system. When pads are worn, the CHANGE BRAKE PADS message displays in the Driver Information Center. See Brake System Messages on page 5‑36.
