Solution

1. Preparation

Gather necessary tools: clean rag, funnel (if needed), and brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
Ensure the vehicle is on a flat surface and the engine is cool.

2. Inspect and Clean Reservoir

Remove the cap from the brake fluid reservoir carefully. Be cautious not to let dirt or contaminants enter the reservoir.
Wipe the cap and around the opening with a clean rag to prevent contamination.

3. Check Fluid Level

Look at the fluid level against the minimum and maximum indicators on the side of the reservoir.
If the fluid is below the minimum line, proceed to top it off.

4. Top Off Brake Fluid

Using a funnel, carefully add the appropriate brake fluid until it reaches the maximum line.
Avoid overfilling; ensure the fluid does not exceed the maximum line.

5. Reassemble

Replace the reservoir cap securely to prevent moisture and contaminants from entering.
Close the hood of the vehicle.
