Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Wheel Removal

Sub-steps:
1. Loosen the lug nuts on the front wheels slightly before lifting the vehicle.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheels.

3. Brake Inspection

Sub-steps:
1. Inspect the brake rotors for warping or scoring. Replace if necessary.
2. Check the brake pads for uneven wear; replace if they are worn down or damaged.
3. Clean the brake caliper and rotor surface with brake cleaner.

4. Rotor Resurfacing or Replacement

Sub-steps:
1. If rotors are warped, either resurface them (if within specifications) or replace them.
2. For resurfacing, mount the rotors on a brake lathe and follow manufacturer guidelines for specifications.
3. If replacing, install new rotors and torque to specified values (typically around 80-100 ft-lbs).

5. Reassembly

Sub-steps:
1. Reinstall brake pads into the caliper.
2. Reattach the wheels and hand-tighten the lug nuts.
3. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even torque.

6. Test Drive

Conduct a test drive to ensure the vibration issue is resolved and brakes function properly.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Dial indicator (for rotor runout measurement)
Brake lathe (if resurfacing rotors)

Parts Required:

Brake rotors (if replacement is needed)
Brake pads (if replacement is needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always disconnect the battery before working on the braking system.
Ensure the vehicle is securely lifted before working underneath it.
