Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel Assembly

Sub-steps:
1. Loosen lug nuts while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket.
2. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the brake pads from the caliper bracket.
4. Check the rotor for warping using a run-out gauge; if warped, replace the rotor.
5. If the rotor is in good condition, clean it with brake cleaner and a wire brush.
6. Install new brake pads if worn or damaged, ensuring they are properly seated in the caliper bracket.
7. Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

4. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications (usually 76-83 ft-lbs).

5. Final Checks

Perform a test drive to ensure the vibration has been resolved.
Check for any unusual noises or performance issues post-repair.
