Brake System Inspection:
- Check brake pads for wear; replace if they are below the minimum thickness (usually 3mm).
- Inspect brake calipers for sticking or overheating; replace if necessary.

3. Address Fluid Leaks

Identify and Repair Leaks:
- Use a flashlight to trace leaks to their source.
- Replace any damaged hoses or seals (e.g., oil pan gasket, transmission seals, etc.).

4. Exhaust System Inspection
