Solution

1. Preparation

Gather necessary tools and safety equipment.
Tools required:
- Brake fluid (DOT 3 or DOT 4, as specified in the owner's manual)
- Wrench set
- Brake line wrench (for tight fittings)
- Clean rags
- Safety goggles and gloves

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the master cylinder reservoir.
Check the fluid level against the "Max" and "Min" indicators.
If the fluid is low, refill it to the appropriate level with the correct type of brake fluid.

3. Visual Inspection of Brake Components

Start at the master cylinder and inspect the brake lines leading to the wheels.
- Look for any cracks, corrosion, or wetness.
Follow the lines to the brake calipers and wheel cylinders.
- Check for any signs of fluid on the exterior of these components.

4. Check Brake Calipers and Wheel Cylinders

If the vehicle is equipped with disc brakes, inspect the calipers.
- Look for wet spots or fluid leaking from the seals.
If the vehicle has drum brakes, remove the drum to inspect the wheel cylinder for leaks.

5. Inspect the Brake Booster

Check the brake booster for fluid leaks, which may indicate a failed seal.
If fluid is found on the brake booster, it may require replacement.

6. Clean Up

Wipe away any spilled brake fluid, as it can damage paint and other materials.
Dispose of any waste fluid responsibly.
