Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, run-out gauge, torque wrench, basic hand tools.
Safely lift and support the vehicle on jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Use a run-out gauge to check the brake rotor for warping. If the measurement exceeds manufacturer specifications, the rotor needs to be replaced.
2. If necessary, remove the brake caliper by unbolting it and securing it away from the rotor (do not stretch brake lines).
3. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install the new rotor, ensuring it is properly aligned and secured with retaining screws.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the brake pads for wear indicators; replace if they are below the minimum thickness.
2. Remove the old brake pads from the caliper bracket.
3. Lubricate the caliper bracket and install new pads in the correct orientation.
4. Reattach the caliper over the new pads and tighten bolts to manufacturer torque specifications.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
2. If any components are damaged or exhibit excessive play, replace them as necessary.
3. Tighten all fasteners to the manufacturer's specifications.

5. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop to ensure proper alignment.
2. Have the wheels balanced if they were removed during the brake service.
