Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, caliper tool, runout gauge.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Gather all necessary tools and safety equipment (gloves, goggles).

2. Lift Vehicle

Sub-steps:
- Use the jack to lift the front or rear of the vehicle depending on where the vibration is most felt.
- Secure the vehicle on jack stands to ensure stability.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the wheel using the lug wrench.
- Detach the brake caliper using the appropriate socket, being careful not to damage the brake line.
- Remove the brake rotor and check for warping using the runout gauge.
- If warped, replace with new rotors ensuring they meet OEM specifications.
- Reinstall the rotor and caliper, and torque bolts to manufacturer specifications (typically around 75-85 ft-lbs).

4. Inspect and Replace Brake Pads

Sub-steps:
- Check the thickness of the brake pads; replace if below 3mm.
- Ensure pads are not glazed or contaminated; replace if necessary.
- Apply brake grease to the back of the pads to reduce noise and ensure proper fit.

5. Check Wheel Lug Nut Torque

Sub-steps:
- Before reinstalling the wheel, ensure lug nuts are clean and free of debris.
- Reinstall the wheel and hand-tighten lug nuts.
- Use a torque wrench to tighten to the manufacturer’s specifications (usually around 76-81 ft-lbs).

6. Final Reassembly

Sub-steps:
- Lower the vehicle off the jack stands using the jack.
- Test the brakes by pressing the pedal several times before driving to ensure proper function.
