Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, OBD-II scanner, brake rotor gauge.
Ensure the vehicle is on a flat surface and set the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Loosen lug nuts on the front wheels and raise the vehicle with a jack.
2. Secure the vehicle on jack stands.
3. Remove the front wheel.
4. Inspect the brake rotors for warping using a rotor gauge; replace if necessary.
  - Parts Required: New brake rotors.
5. If replacing, unbolt the caliper and hang it using a wire to avoid strain on the brake line.
6. Remove the rotor and install the new one, ensuring it is properly seated.

3. Inspect and Replace Brake Pads

Sub-steps:
1. While the caliper is removed, inspect brake pads for excessive wear.
  - Replace if thickness is below the minimum recommended level.
  - Parts Required: New brake pads.
2. Clean the caliper and apply brake grease to the caliper slides.
3. Reinstall the caliper over the new pads and torque the bolts to the manufacturer's specifications.

4. Suspension Inspection

Sub-steps:
1. Inspect all suspension components for wear, especially tie rods and bushings.
2. Replace any damaged or worn components.
  - Parts Required: New tie rods, control arms, or bushings as needed.

5. Wheel Alignment and Balancing

Sub-steps:
1. After reassembling, have the wheels aligned and balanced at an automotive shop.
2. Ensure proper torque on lug nuts after wheel installation.
