Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, wire brush.
Raise the vehicle using the jack and secure it on jack stands.
Remove the wheel using the lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with the socket set and carefully lift the caliper off the rotor.
- Inspect the brake pads; if they are less than 3mm thick or have uneven wear, replace them.
- Clean the caliper bracket and pad contact points with brake cleaner and a wire brush.
- Install new brake pads, ensuring they seat properly in the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor surface for any grooves, scoring, or warping.
- If damaged, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are centered on the hub.
- Torque the retaining screws to the manufacturer's specifications.

4. Reassemble Brake Components

Sub-steps:
- Reposition the brake caliper over the new pads and rotor.
- Reinstall caliper bolts and torque them to the specified value.
- Reinstall the wheel and hand-tighten all lug nuts.

5. Final Checks

Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specification.
Pump the brake pedal several times to ensure the brake pads are seated properly.
