Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Tire iron
- Brake pad gauge
- Torque wrench
- Brake cleaner
Safety Warnings:
- Ensure the vehicle is on a flat surface and secure it with wheel chocks.
- Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts on the wheel using a tire iron.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake rotor, ensuring no brake lines are stressed.
Remove the old brake pads from the caliper bracket.
Inspect the caliper guide pins for wear and lubricate them if needed.
Install new brake pads, ensuring they are oriented correctly.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for any grooves, warping, or heavy rust.
If damaged, remove the rotor by unscrewing the retaining screws (if applicable).
Install new rotors, ensuring they are clean and properly seated.
Torque the rotor retaining screws to the manufacturer's specifications (if applicable).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 100-120 ft-lbs).
Pump the brake pedal several times to seat the brake pads before driving.
