Solution

1. Preparation

Tools Required: Clean rags, flashlight, and a container for any spilled brake fluid.
Park the vehicle on a level surface and ensure the engine is turned off.
Allow the brake system to cool if it has been used recently.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir.
If low, clean around the cap and remove it to inspect for contamination.

3. Examine Brake Lines

Trace the brake lines from the master cylinder to each wheel.
Look for any visible damage or signs of fluid seeping from connections.
If you find damage, mark the area for replacement.

4. Check Brake Calipers and Wheel Cylinders

Inspect each brake caliper for signs of brake fluid leakage.
If equipped, check the wheel cylinders for any signs of wetness or fluid accumulation.
Clean any visible fluid with rags to allow better visual inspection.

5. Inspect Master Cylinder

Examine the master cylinder for any signs of fluid leaks around the seals.
Look particularly around the area where the brake lines connect.
If leaks are found, consider replacing the master cylinder.

6. Check Brake Booster

If applicable, inspect the brake booster for any signs of fluid seeping.
Look for wetness or discoloration around the booster area.
