• Examine for brake fluid leaks: Look for any puddles or wet spots under the vehicle, especially near the wheels and brake lines. Repair any leaks to ensure the effectiveness of the braking system.
• Ensure no coolant leaks: Check for coolant puddles under the vehicle or signs of leakage in the engine compartment. Repair any leaks to prevent overheating and engine damage.
