Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

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 of the pads; replace if below 3mm.
Remove Brake Caliper:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of new pads and install them into the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is damaged, remove any retaining screws and slide the rotor off the hub.
Install New Brake Rotor:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it.

5. Reassemble and Test

Reattach Brake Caliper:
- Position the caliper over the new brake pads and secure it with bolts. Torque to manufacturer's specifications (typically around 25-30 Nm).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle:
- Remove the jack stands and lower the vehicle to the ground.
Torque Lug Nuts:
- Torque the lug nuts to the manufacturer’s specifications (usually around 100-120 Nm).
