3. Brake Inspection

Remove Wheel:
- Using a jack and jack stands, lift the vehicle and remove the wheel.
Inspect Brake Components:
- Check brake pads, rotors, and calipers for signs of burning or excessive wear.
- Replace any worn components with new parts as necessary.

4. Electrical System Inspection

Inspect Wiring:
- Visually inspect wiring harnesses and connectors in the engine bay for damage.
- Repair or replace any damaged wiring to prevent electrical shorts.

5. Reassemble and Test

Reattach any components removed for inspection.
Reconnect the battery.
Start the vehicle and allow it to reach operating temperature while monitoring for burning smells or leaks.
