Solution

1. Preparation

Gather necessary tools and materials.
Tools Required: Clean cloth, funnel, new brake fluid (DOT 4 specification).
Safety Warnings: Ensure the engine is off and the vehicle is on a flat surface.

2. Inspecting the Brake Fluid Reservoir

Locate the brake fluid reservoir cap and clean the area around it to prevent contamination.
Carefully remove the cap from the reservoir.

3. Checking the Fluid Level

Examine the fluid level inside the reservoir. It should be between the minimum and maximum marks.
If the fluid is below the minimum mark, proceed to the next step.

4. Adding Brake Fluid

Using a funnel, add new brake fluid (ensure it meets DOT 4 specification) to the reservoir until it reaches the maximum mark.
Avoid overfilling, as this can lead to brake system issues.

5. Finalizing

Replace the reservoir cap securely.
Clean any spilled brake fluid with a cloth, as it can damage paint and surfaces.
