Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Tire iron
- OBD-II scanner
- Torque wrench
- Multimeter (if electrical components are suspected)
Safety Warnings: Ensure the vehicle is on a flat surface; engage the parking brake before lifting the vehicle.

2. Inspect and Replace Brake Components

Lift the Vehicle: Use the jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Use a tire iron to remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of brake pads; replace if below manufacturer specifications.
- Inspect rotors for grooves or warping; replace if necessary.
Replace Components (if needed):
- Remove the caliper using a socket set.
- Replace pads with new ones, ensuring they are seated correctly.
- Reinstall the caliper and torque to manufacturer specifications.

3. Inspect Tire Condition

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the recommended PSI.
Inspect Tread Wear: Look for uneven wear patterns; replace tires if significantly worn.
Balance Tires: If vibrations are present, consider having the tires balanced by a professional.

4. Inspect Suspension Components

Check for Loose Parts: Visually inspect suspension parts for looseness or damage.
Tighten Loose Components: Use a torque wrench to tighten any loose bolts to manufacturer specifications.
Replace Damaged Parts: If any components are damaged (e.g., bushings, struts), replace them as necessary.
