Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen lug nuts slightly with a lug wrench.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if less than 3mm.
- Measure rotor thickness and check for warping.
Replace Brake Pads:
- Remove the caliper by loosening the caliper bolts.
- Slide the caliper off and hang it securely (do not let it dangle by the brake line).
- Remove the old pads and install new pads.
- Reinstall the caliper and torque bolts to manufacturer's specifications (typically around 25-35 Nm).
Replace Rotors (if warped or damaged):
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Install the new rotor, ensuring it sits flush against the hub.
- Torque any retaining screws if applicable.

4. Reinstall Wheel

Place the wheel back on the hub.
Hand-tighten the lug nuts, then lower the vehicle.
Torque the lug nuts to the manufacturer's specifications (typically around 120 Nm).

5. Test Drive

Carefully test drive the vehicle to ensure vibrations are eliminated.
Check for proper brake functionality and listen for any unusual noises.
