Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raise it using jack stands.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; they should be at least 3mm thick.
- Look for uneven wear or cracks.
Replacement:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it, do not let it hang by the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface or Replace Rotors

Inspection:
- Check the rotor for any grooves, warping, or excessive wear.
Resurfacing:
- If the rotor is within specification, use a brake lathe to resurface it.
Replacement:
- If the rotor is too damaged, remove it by unbolting it from the wheel hub.
- Install the new rotor, ensuring it is torqued to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper over the new pads and tighten the caliper bolts to the specified torque.
Reinstall the wheel and lug nuts, tightening in a star pattern to the manufacturer's torque specification.
Reconnect the battery and lower the vehicle.
