Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, dial indicator (for rotor measurement).

2. Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and place it securely on jack stands.
Remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Use a dial indicator to check for warping; acceptable runout is typically less than 0.002 inches.
If warped, proceed to replace the rotors.
Tools Required: Dial indicator.
Parts Required: New brake rotors.

B. Check Brake Pads

Inspect pads for uneven wear; replace if they are worn down below 1/8 inch.
Clean the caliper bracket and pad surfaces with brake cleaner.
Parts Required: New brake pads if needed.

4. Reassemble and Torque Components

Reinstall the rotors and brake pads.
Ensure calipers are properly positioned.
Reinstall wheels, hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications (usually around 80-100 ft-lbs, but verify for your specific model).

5. Test Drive

Conduct a test drive to ensure the vibrations have been resolved.
Monitor for any abnormal noises or issues during braking.
