Solution

1. Preparation

Gather necessary tools: a clean cloth, funnel (if adding fluid), and possibly a flashlight for visibility.
Ensure the vehicle is on a flat surface and the engine is off.

2. Inspect Fluid Level

Look at the side of the brake fluid reservoir to determine if the fluid is between the minimum and maximum level markers.
If the fluid level is below the minimum mark, proceed to add brake fluid.

3. Add Brake Fluid (if necessary)

Remove the reservoir cap by twisting it counterclockwise.
Using a funnel, add the appropriate type of brake fluid (typically DOT 3 or DOT 4) until it reaches the maximum level line.
Avoid overfilling the reservoir; excess fluid can lead to brake system issues.

4. Reassemble

Replace the reservoir cap securely to prevent contamination.
Clean any spilled fluid immediately, as brake fluid can damage paint and other surfaces.
