Solution

1. Preparation

Gather tools and safety equipment, including gloves and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Wheel Removal

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

3. Brake Rotor Inspection and Replacement

Inspect the brake rotor for signs of warping or scoring.
If warped, proceed to remove the caliper by unbolting it from the bracket.
- Tools required: Socket set, ratchet, and possibly a breaker bar for stubborn bolts.
Remove the rotor from the hub by unscrewing any retaining screws and sliding it off.
Install the new rotor, ensuring it is seated properly.
Reattach the brake caliper and torque bolts to manufacturer specifications (usually around 30-40 Nm).

4. Brake Pad Inspection and Replacement

Remove the brake pads from the caliper bracket.
Inspect for uneven wear; replace if necessary.
Apply brake grease to the back of new pads to prevent noise.
Install new pads and reassemble the caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (usually around 100 Nm).
Repeat the process on the other side if necessary.
