Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and materials.
Tools Required: Brake fluid, wrench set, flashlight, cleaning cloths.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and check the fluid level against the "MIN" and "MAX" indicators.
If fluid is low, inspect for leaks in the reservoir and its connections.

3. Examine Brake Lines and Hoses

Trace the brake lines from the master cylinder to each wheel, looking for cracks, corrosion, or wetness along the lines.
Inspect all rubber hoses for signs of wear or damage that could lead to leaks.
Use a flashlight to illuminate hard-to-see areas.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel to gain better access to the brake caliper.
Inspect the caliper for any signs of brake fluid leakage.
Check the wheel cylinder (if applicable) for wetness or signs of seepage.
Clean any excess fluid with a cloth but avoid contaminating brake components.

5. Inspect the Master Cylinder

Check the master cylinder for any external leaks.
Ensure that the mounting bolts are tight and there are no cracks or damage to the cylinder.
If leaks are found, consider replacing the master cylinder.
