Solution

1. Preparation

Gather required tools and parts, and ensure the vehicle is parked on a level surface.
Wear gloves and safety goggles for protection.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect Brake Fluid Reservoir

Locate the brake fluid reservoir under the hood.
Remove the cap and inspect for any cracks or leaks. Clean the area around the cap before removing it to prevent contaminants from entering the reservoir.

3. Examine Brake Lines

Follow the brake lines from the master cylinder to the wheels.
Inspect the lines for any signs of corrosion, kinks, or fluid leakage. Use a wire brush if necessary to clean any dirt away.

4. Check Brake Calipers and Wheel Cylinders

For each wheel, remove the wheel cover (if applicable) and inspect the brake calipers and wheel cylinders.
Look for signs of brake fluid seepage or wetness around the seals and connection points.

5. Inspect Under the Vehicle

Safely lift the vehicle using a jack and secure it with jack stands.
Inspect the ground beneath the vehicle for signs of brake fluid leaks. The fluid is typically clear to light brown in color and has a distinct smell.

6. Perform System Pressure Test

If no leaks are found visually, connect a brake pressure tester to the brake system.
Pressurize the system and monitor for drops in pressure, which may indicate a leak that is not visible.
