Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, OBD-II scanner.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Loosen lug nuts and lift the vehicle using a jack. Secure with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake rotor with a dial indicator; if warping exceeds manufacturer specifications, replace the rotor.
4. If replacement is necessary, remove the caliper by unbolting it and hanging it securely.
5. Remove the rotor, and install the new rotor, ensuring it is seated correctly.
6. Reinstall the caliper, tightening bolts to the manufacturer’s torque specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; if they are worn below the minimum thickness, replace them.
2. Remove the old brake pads from the caliper bracket.
3. Apply brake grease to the back of the new pads and install them in the caliper bracket.
4. Reinstall the caliper over the new pads.

4. Check Suspension Components

Sub-steps:
1. Inspect control arms, ball joints, and bushings for any signs of wear or damage.
2. Replace any worn suspension components as necessary.
3. Ensure all fasteners are tightened to manufacturer specifications.

5. Wheel Alignment and Balance

Sub-steps:
1. After completing brake and suspension work, take the vehicle to a professional for wheel alignment and balancing.
2. Verify that all tires are properly inflated.
