• Brake pads should be replaced when worn to two mm of pad thickness. New pads are 10 mm thick. • In addition, brake pad inspection is required any time the tires are removed. 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 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 8-17. The ZR1 also has an electronic brake pad wear sensor system. When pads are worn, the CHANGE BRAKE PADS message displays in the Driver Information Center. See DIC Warnings and Messages on page 4-51. 6-49
