Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery for safety.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection:
- Check the brake pads for uneven wear or insufficient material thickness (below 3mm indicates replacement).
Replacement:
- Remove the caliper bolts using the appropriate socket size.
- Slide the caliper off the rotor and support it with a bungee cord or similar tool (do not 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/Replace Rotors

Inspection:
- Check the rotors for scoring or uneven wear.
Resurfacing/Replacement:
- If scoring is present and exceeds the manufacturer's specifications, consider resurfacing or replacing the rotors.
- If replacing, remove the rotor retaining screws and pull the rotor off the hub.
- Install the new rotor and torque the retaining screws to the manufacturer’s specified value.

5. Reassemble Components

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications.
