Solution

1. Preparation

Gather necessary tools such as a flashlight for better visibility.
Ensure the vehicle is parked on a level surface for accurate fluid level reading.

2. Inspect Brake Fluid Reservoir

Open the brake fluid reservoir cap carefully to avoid contamination.
Use a clean cloth to wipe the cap and surrounding area to prevent debris from entering the reservoir.
Check the fluid level against the minimum and maximum markers on the reservoir. If low, proceed to the next step.

3. Add Brake Fluid

Determine the appropriate type of brake fluid required (usually DOT 3 or DOT 4; refer to the owner's manual for specifics).
Using a funnel, carefully add brake fluid until it reaches the maximum fill line.
Avoid overfilling, as it may cause fluid to overflow when the brakes are applied.

4. Replace Cap and Clean Up

Reinstall the brake fluid reservoir cap securely.
Clean any spilled fluid from the reservoir and surrounding area to prevent damage to painted surfaces.
Dispose of any used materials properly.
