Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, caliper tool, measuring caliper.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on ABS components.

2. Inspect Brake Components

Sub-steps:
- Remove the wheel using the lug wrench.
- Inspect the brake pads for thickness and uneven wear; replace if less than 3 mm.
- Check the brake rotors for warping with a measuring caliper; replace if runout exceeds specifications (usually 0.002 inches).
- Clean the rotor surface with brake cleaner.

3. Replace Brake Pads and Rotors

Sub-steps:
- Remove the caliper bolts and slide the caliper off the rotor.
- Use a caliper tool to compress the caliper piston if replacing pads.
- Remove the old pads and install new ones, ensuring proper orientation.
- Install new rotors if necessary, following torque specifications for the rotor bolts (if applicable).

4. Check Suspension and Steering Components

Sub-steps:
- Inspect all suspension components for damage or looseness, such as tie rods, control arms, and bushings.
- Tighten any loose bolts to manufacturer specifications.
- Replace any worn or damaged parts.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
- Reconnect the battery if it was disconnected.
- Test drive to ensure the vibration issue is resolved.
