Solution

1. Preparation

Tools Required: Socket set, jack stands, lug wrench, brake cleaner, torque wrench, caliper tool.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Brake Pad and Rotor Inspection

Inspect Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
- Check the thickness of the brake pads; replace them if they are below the manufacturer’s specification (typically 3mm or less).
Inspect Brake Rotors:
- Check the surface of the rotors for warping or scoring using a straightedge or machinist's ruler.
- If warped, replace the rotors; if scored but not warped, they may be machined if within thickness specifications.

4. Reassemble Components

Clean the rotor surface with brake cleaner to remove any dust or debris.
If pads were replaced, install new brake pads into the caliper bracket.
Reinstall the caliper over the new pads, ensuring it slides smoothly.
Torque the caliper bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).

5. Wheel Reinstallation

Place the wheel back onto the hub.
Hand-tighten the lug nuts initially, then lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the manufacturer’s specification (typically 76 ft-lbs).
