Inspect the Rotors:
- Measure the thickness of the rotors; replace if below manufacturer specifications.
- Check for warping by measuring run-out with a dial indicator.
Remove Rotors:
- Unscrew the caliper bracket bolts and remove the caliper.
- Detach the rotor from the hub by removing the retaining screws or using a hammer to gently tap it off.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotors onto the hub, ensuring they are seated properly.

4. Replace Brake Pads

Remove Brake Pads:
- Slide the old pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to prevent squeaking.
