Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, safety glasses.
Lift the vehicle and secure it on jack stands. Ensure the workspace is clean and organized.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Lift the caliper off the rotor and inspect the brake pads for thickness and wear.
- Replace pads if they are worn below the manufacturer's specifications.
Brake Rotors:
- Measure the rotor thickness with a micrometer. If below the minimum thickness, replace the rotor.
- Check for warping by using a dial indicator; if warped beyond specifications, replace the rotor.
- If the rotor is reusable, clean it with brake cleaner and ensure the surface is smooth.

4. Reassemble Brake Components

Place new or resurfaced rotors back onto the hub.
Reinstall the brake caliper over the pads and rotor, ensuring it is aligned properly.
Torque the caliper bolts to the manufacturer's specifications (check the service manual for specific torque values).

5. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to torque the lug nuts to specifications.

6. Final Checks

Inspect suspension components for any visible damage or excessive play. Replace any worn parts as needed.
Check alignment and wheel balance if necessary.
