Solution

1. Preparation

Gather necessary tools and parts.
Ensure the workspace is clean and safe.
Wear safety goggles and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness; replace if less than 3mm.
Remove Old Pads:
- Remove caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
Install New Pads:
- Apply a thin layer of brake grease to the back of new brake pads to reduce noise.
- Install the new pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Inspect Rotors:
- Check for scoring or excessive wear. If warped, resurface or replace as necessary.
Resurface (if applicable):
- Use a brake lathe to machine the rotor surfaces.
Replace (if applicable):
- Remove the caliper bracket and rotor bolts.
- Replace with new rotors and torque bolts to manufacturer specifications.

5. Reassemble Components

Reattach Caliper:
- Slide the caliper back over the new brake pads.
- Tighten caliper bolts to manufacturer specifications.
Reinstall Wheel:
- Mount the wheel back onto the hub.
- Hand-tighten lug nuts and lower the vehicle.
- Torque lug nuts to manufacturer specifications using a torque wrench.
