Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools and parts.
Safety warning: Ensure the engine is off and the vehicle is cool.

2. Remove Wheel

Loosen lug nuts slightly before lifting the vehicle with a jack.
Securely raise the vehicle and place jack stands underneath.
Remove the wheel completely.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang from the brake line).
- Inspect the brake pads for wear; replace if they are below the minimum thickness.
Brake Rotors:
- Check the rotor surface for warping or uneven wear using a dial gauge.
- If warped, replace the rotor; if permissible, resurface it if within manufacturer specifications.

4. Reassemble Components

Reinstall the caliper over the new or resurfaced rotor.
Tighten caliper bolts to manufacturer specifications (usually around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Remove jack stands and lower the vehicle.
Torque lug nuts to the specified value (typically 90-120 Nm, depending on the model).
