Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

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

3. Remove Wheel

Use a socket set to remove lug nuts and take off the wheel to access the brake system.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor.
- Check pads for wear; replace if they are less than 3mm thick.
Replace Brake Pads:
- Slide new brake pads into position.
- Ensure they are properly aligned and seated.

5. Inspect and Replace Brake Rotors (if necessary)

Remove Rotor:
- Remove any retaining screws or clips holding the rotor.
- Slide the rotor off the hub.
Install New Rotor:
- Place the new rotor onto the hub.
- Secure it with screws or clips as required.

6. Reassemble Brake Components

Slide the caliper back over the new pads and rotor.
Reinstall caliper bolts and torque to manufacturer's specifications (typically around 25-30 ft-lbs).
Reattach the wheel and lug nuts, ensuring they are torqued properly.
