Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Wheel Removal

Use a jack to lift the vehicle and support it with jack stands.
Remove the wheel lug nuts with a socket wrench.
Take off the wheel and set it aside.

3. Brake Component Inspection

Inspect the brake rotor:
- Use a micrometer to measure the rotor thickness.
- Look for any signs of warping or scoring.
Inspect the brake pads:
- Measure the pad thickness using a caliper.
- Replace pads if they are worn below the manufacturer’s specification (typically 3mm).

4. Brake Rotor Resurfacing or Replacement

If rotors are warped, they should either be resurfaced or replaced.
- For resurfacing:
  - Remove the rotors from the hub by unscrewing the retaining screws.
  - Take them to a machine shop for resurfacing.
- For replacement:
  - Install new rotors by aligning them with the hub and securing with retaining screws.

5. Reassemble Brake Components

Reinstall brake pads into the caliper bracket.
Reattach the caliper over the brake pads and secure it with bolts.
Reinstall the wheel and lug nuts, tightening in a star pattern to the specified torque (typically 80-100 ft-lbs).

6. Wheel Alignment and Balance

Have the wheels balanced and aligned by a professional to ensure even tire wear and proper handling.

7. Final Check

Lower the vehicle off the jack stands and remove the jack.
Check brake fluid levels and top up if necessary.
