Solution

1. Preparation

Tools Required:
- Flashlight
- Brake fluid
- Clean rags
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum marks on the reservoir.
If low, top off with the appropriate brake fluid type specified in the owner's manual.

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for any cracks, abrasions, or signs of moisture.
Pay special attention to connection points and fittings for leaks.

4. Check Brake Calipers and Wheel Cylinders

Inspect each wheel's brake caliper for signs of fluid leakage.
Examine the wheel cylinders for any signs of brake fluid weeping.
Use a clean rag to wipe around the caliper and cylinder to reveal any hidden leaks.

5. Inspect Master Cylinder

Check the master cylinder for any external leaks.
Look for fluid buildup around the base of the master cylinder.
If leaks are suspected, clean the area and monitor for new fluid accumulation.

6. Perform a Pressure Test

If no leaks are visible, perform a brake system pressure test.
Use a brake pressure gauge to check for any drops in pressure, indicating a hidden leak.
Follow the manufacturer's instructions for the pressure test procedure.
