Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; replace if less than 3mm.
- Look for uneven wear patterns.
Remove Old Brake Pads:
- Unbolt the caliper bracket using the appropriate socket.
- Carefully slide the caliper off and support it with a bungee cord (do not hang by the brake line).
Install New Brake Pads:
- Apply brake grease to the back of the new pads.
- Slide the new pads into place.

5. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is scored or warped, unbolt it from the hub.
Install New Brake Rotor:
- Clean the new rotor with brake cleaner.
- Secure the new rotor to the hub, torquing bolts to manufacturer's specifications.

6. Reassemble and Test

Reattach the caliper and wheel.
Tighten lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and perform a test brake to ensure proper function.
