- Check the coolant reservoir for level; add coolant if necessary.
Brake Fluid:
- Inspect the brake fluid reservoir; ensure it's at the proper level.

3. Component Inspection

Inspect Wiring and Connectors:
- Visually examine all wiring harnesses for signs of damage or melting.
- Repair or replace any damaged wires or connectors.
Check Exhaust System:
- Inspect for any leaks or damage; repair or replace components as necessary.

4. Brake System Maintenance

Inspect Brake Pads and Rotors:
- Remove the wheel to access the brake assembly.
- Check the thickness of the brake pads; replace if worn down.
- Inspect the rotors for warping or overheating; replace if necessary.

5. Reassembly and Testing

Reconnect the battery once all inspections and repairs are completed.
Lower the vehicle and start the engine; allow it to run and monitor for any abnormal smells or sounds.
