Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery if working on the brake system for safety.

2. Inspect Brake Components

Remove the front wheels using a socket set.
Inspect brake pads for uneven wear or damage; replace if necessary.
Measure the thickness of the brake rotors. If the thickness is below the manufacturer's specifications, replace the rotors.
Check for any scoring or warping on the rotors using a straight edge and a feeler gauge; if warped, resurface or replace the rotors.

3. Address Suspension Issues

Inspect all suspension components for damage or excessive play.
Replace any worn or damaged parts such as ball joints or tie rods.
If necessary, perform a wheel alignment to ensure proper handling and tire wear.

4. Reassemble

Reinstall the brake components and wheels.
Ensure all lug nuts are torqued to the manufacturer's specifications (typically 76-100 ft-lbs for Toyota).
