Fluid Leaks
- For any leaking fluids found, identify the source.
- Replace any damaged seals or gaskets.
- If oil is leaking, replace the oil filter and change the engine oil.

3. Brake System Inspection

Brake Pads and Rotors
- Remove the wheel and inspect the brake pads and rotors for excessive wear.
- Replace burnt brake pads and machine or replace rotors as necessary.

4. Exhaust System Repair

Inspect the exhaust for any leaks or damaged components.
Replace any damaged gaskets or pipes as needed.
