Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and safely elevated using jack stands.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid stress on the brake line.
- Inspect the brake pads for wear; if they are less than 3mm thick, replacement is necessary.
Replacement:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new brake pads to prevent noise.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Examine the rotors for any grooves or scoring.
- If the rotor thickness is below the manufacturer's minimum specification or if they are warped, they should be replaced.
Replacement:
- Remove the caliper bracket bolts using a socket wrench.
- Slide the caliper bracket off and remove the rotor.
- Install the new rotor on the hub, ensuring it is seated properly.

5. Reassemble and Test

Reattach the caliper bracket and caliper, ensuring bolts are torqued to the manufacturer's specifications (usually around 79 lb-ft for caliper bolts).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.
Reconnect the negative battery terminal.
