1. Measure rotor thickness using a micrometer to ensure they are within specifications.
2. Check for scoring, warping, or overheating signs.
3. Resurface or replace rotors as needed.
Tools Required:
- Micrometer
- Brake cleaner
- Torque wrench (for reinstallation)

5. Examine Brake Calipers

Sub-steps:
1. Check for any signs of leakage around the caliper seals.
2. Ensure the caliper is not seized by moving the piston in and out.
3. Replace calipers if they show signs of malfunction.
Tools Required:
- Socket set
- Brake caliper tool (if necessary)

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
