How do you replace the rotors on a Cadillac CTS?

To replace the rotors on a Cadillac CTS, first, safely lift and secure the vehicle, then remove the wheel to access the brake components. Next, remove the caliper by unbolting it from the bracket and hang it using a wire to avoid stress on the brake line. Take off the old rotor, clean the hub surface, and install the new rotor, ensuring it is properly seated. Finally, reattach the caliper, replace the wheel, and lower the vehicle before testing the brakes.
