Solution

1. Preparation

Tools Required: Clean rag, funnel, brake fluid (DOT 3 or DOT 4), gloves.
Safety Warnings: Ensure the engine is off and cool before working under the hood. Wear gloves to protect skin from brake fluid.

2. Check Fluid Level

Remove the cap from the brake fluid reservoir.
Wipe the area around the reservoir cap with a clean rag to prevent contamination.
Check the fluid level; it should be between the "MIN" and "MAX" marks.

3. Refill Brake Fluid

If the fluid is below the "MIN" mark, use a funnel to carefully add the appropriate brake fluid (DOT 3 or DOT 4) to the reservoir.
Fill until the fluid reaches the "MAX" mark, taking care not to overfill.
Replace the reservoir cap securely.

4. Clean Up

Wipe any spilled brake fluid immediately with a clean rag, as it can damage vehicle paint and surfaces.
Dispose of any used rags properly.
