Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, socket set, brake cleaner.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the braking system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Use the dial indicator to measure the runout on the brake rotor. If it exceeds manufacturer specifications, it is warped and needs replacement.
2. Remove the brake caliper by unbolting it from its mounting bracket.
3. Carefully slide the caliper off the rotor and secure it to avoid stressing the brake line.
4. Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
5. Install the new rotor, ensuring it is seated correctly. Torque the retaining screws to the manufacturer's specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Examine the brake pads for wear. If the thickness is below manufacturer's specifications, replace the pads.
2. Remove the old brake pads by sliding them out of the caliper bracket.
3. Lubricate the caliper bracket and install the new pads, ensuring they are correctly positioned.
4. Reinstall the caliper over the new pads and torque the caliper bolts to the recommended specifications.

4. Inspect Suspension Components

Sub-steps:
1. Check control arms and bushings for any signs of wear or damage. Replace if necessary.
2. Inspect wheel bearings for play or roughness. Replace if they do not spin smoothly.
3. Tighten any loose suspension components to the specified torque values.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.
