Solution

1. Preparation

Gather necessary tools and safety equipment.
Tools Required: Brake fluid tester, flashlight, wrench set, rags for cleaning.
Safety Warnings: Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect the Brake Fluid Reservoir

Locate the brake fluid reservoir, typically near the driver's side of the engine compartment.
Check the fluid level against the minimum and maximum marks on the reservoir.
Look for cracks or damage on the reservoir itself.

3. Check Brake Lines and Hoses

Follow the brake lines from the master cylinder to the wheels.
Inspect all visible portions for signs of wear, such as fraying or bulging.
If any damage is found, proceed to replace the affected line or hose.

4. Examine Brake Calipers and Wheel Cylinders

Remove the wheel to access the brake caliper.
Inspect the caliper for fluid leaks, particularly around the piston and seals.
If fluid is present, replace the caliper or rebuild it as necessary.

5. Inspect the Master Cylinder

Check for fluid leakage around the master cylinder and its mounting points.
If leaks are detected, replace the master cylinder.
Ensure proper bleeding of the brake system after replacement.
