Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear (gloves, goggles).

2. Remove Front Wheels

Loosen the lug nuts on both front wheels using a socket set.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Pads and Rotors

Inspect Brake Pads: Remove the caliper bolts with a socket wrench and slide the caliper off. Check for uneven wear and replace if necessary.
Inspect Rotors: Check the surface of the rotors for warping or scoring. If warped, replace the rotors.
Replace Brake Pads: If replacement is needed, remove the old pads and install new ones, ensuring they are properly seated.
Torque Specifications: Torque caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

4. Reinstall Wheels

Reattach the front wheels, hand-tightening the lug nuts initially.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s torque specifications (usually around 100-120 ft-lbs).

5. Test the Brake System

Start the vehicle and perform a brake test at low speed to ensure the vibration has been resolved.
Check for any unusual noises or additional vibrations.
