Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use a hydraulic jack and jack stands to lift the vehicle securely.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect for Warping:
- Use a run-out gauge to check rotor flatness. If warped, proceed to replace.
Remove Old Rotors:
- Unbolt the caliper and secure it (do not let it hang by the brake line).
- Remove the rotor by unscrewing the retaining bolts.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotor and torque the retaining bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Remove Old Pads:
- Remove the caliper bracket and the old brake pads.
Install New Pads:
- Lubricate the caliper slide pins and install new pads.
- Reattach the caliper and ensure it moves freely.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Torque the wheel lug nuts to the manufacturer's specifications.
