Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake pad spreader
- Caliper tool (if necessary)
Ensure the vehicle is on a level surface.
Disconnect the negative battery terminal for safety.

2. Wheel Removal

Loosen lug nuts slightly before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Inspection

Inspect Brake Pads:
- Remove the caliper bolts and lift the caliper off the rotor.
- Check the thickness of the brake pads; replace if below manufacturer's specifications.
Inspect Brake Rotors:
- Check the rotor surface for warping or scoring using a runout gauge.
- If warped, either resurface or replace the rotor as necessary.
Inspect Calipers:
- Look for signs of sticking or leaking; replace if necessary.

4. Reassembly

Reinstall the caliper over the new or inspected brake pads.
Tighten caliper bolts to manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Finalize

Lower the vehicle back to the ground.
Torque the lug nuts to the specified value in a crisscross pattern.
Reconnect the negative battery terminal.
