Tools Required: Torque wrench, socket set, brake rotor tool
Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove the caliper by unbolting it from the bracket and support it with a bungee cord to avoid stressing the brake line.
3. Remove the brake pads from the caliper.
4. Unbolt the rotor from the hub, if necessary, and remove it.
5. Clean the hub surface with a wire brush and install the new rotor.
6. Reinstall the caliper and brake pads, ensuring proper alignment.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader tool, torque wrench, socket set
Sub-steps:
1. Follow the steps from "Inspect and Replace Brake Rotors" to access the brake assembly.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads, ensuring they are properly seated.
4. Reassemble the caliper and secure it with the appropriate torque specifications.

4. Inspect Suspension Components

Tools Required: Wrench set, jack and jack stands, torque wrench
Sub-steps:
1. Lift the vehicle and securely support it with jack stands.
2. Visually inspect control arms, bushings, and tie rods for wear or damage.
