Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the battery (if working on electrical components).

2. Inspect Brake Components

Remove Wheel:
- Loosen lug nuts slightly while the vehicle is on the ground.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel.
Check Brake Pads:
- Inspect the thickness of the brake pads; replace if less than 1/4 inch.
- Check for uneven wear patterns.
Examine Brake Rotors:
- Measure the rotor thickness using a micrometer.
- Check for warping by spinning the rotor and observing for any wobbling.
- Replace or resurface rotors as necessary.

3. Tire Inspection

Check Tire Condition:
- Inspect tires for uneven wear or damage.
- Measure tread depth to ensure it meets safety standards.
- Replace tires if they are worn unevenly or below the legal limit.
Wheel Alignment and Balance:
- Perform a wheel alignment check and adjust as necessary.
- Have the wheels balanced to ensure even tire wear and proper handling.

4. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specified value (usually around 80-100 ft-lbs for RAV4).
Reconnect the battery.
