Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect Brake Pads

Remove the wheel using a socket set.
Check the brake pad thickness; replace if below 3mm.
Clean any debris or dust from the brake pads with brake cleaner.

3. Check Brake Rotors

Use a dial indicator to measure rotor runout; replace if out of specification (usually more than 0.002 inches).
If warped, remove the rotors using a torque wrench to unscrew the caliper bolts.
Resurface or replace the rotors as necessary.

4. Wheel Alignment and Balance

Inspect the tire condition; replace if unevenly worn.
Check wheel balance using a tire balancer; adjust weights as needed.
If misaligned, adjust alignment according to manufacturer specifications.

5. Reassemble and Test

Reinstall the brake components and wheels securely.
Reconnect any electrical connectors that may have been detached.
Lower the vehicle and perform a test drive to ensure the issue is resolved.
