Solution

1. Preparation

Tools Required:
- Brake fluid
- Clean rag or paper towel
- Safety glasses
- Gloves
Ensure the vehicle is parked on a level surface and the engine is off. Allow the vehicle to cool down if it has been recently driven.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is below the minimum mark, it indicates a potential leak.
Clean the area around the reservoir cap before removing it to prevent contamination.
Top off the brake fluid with the proper type (DOT 3 or DOT 4) if necessary.

3. Check Brake Lines

Inspect the brake lines visually from the master cylinder to each wheel.
If you find any signs of corrosion, fluid, or damage, mark the areas for repair or replacement.

4. Inspect Brake Calipers

Remove the wheel to gain access to the brake calipers if a leak is suspected at this location.
Look for wetness or fluid around the caliper seals.
If fluid is present, the caliper may need to be rebuilt or replaced.

5. Examine Brake Master Cylinder

Inspect the master cylinder for leaks, especially around the gasket and connection points.
If a leak is found, the master cylinder may need to be replaced.

6. Reassembly

If any components were removed, reassemble them carefully.
Ensure all connections are secure and the brake fluid reservoir cap is tightly closed.
