Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- Caliper tool
- Socket set
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported with jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts on the affected wheel while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Measure the thickness of the brake pads; replace if below manufacturer specifications (usually 3mm).
Remove Brake Caliper:
- Remove the caliper mounting bolts using a socket wrench.
- Carefully slide the caliper off the rotor and hang it using a bungee cord or wire (do not let it hang by the brake line).
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the back of the new pads.
- Insert the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any deep grooves or warping; replace if necessary.
Remove Rotors:
- If replacement is needed, remove the caliper bracket bolts and take off the caliper bracket.
- Remove any retaining screws and slide the rotor off the wheel hub.
Install New Rotors:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with retaining screws.

5. Reassemble and Test

Reattach Caliper:
- Reinstall the caliper over the new pads and rotor, ensuring it is correctly positioned.
- Tighten caliper mounting bolts to the manufacturer’s torque specifications.
Reinstall Wheel:
- Place the wheel back on the hub, hand-tighten the lug nuts, and lower the vehicle.
- Once on the ground, torque the lug nuts to the manufacturer’s specifications.
