1. Locate the brake fluid reservoir. It is usually located under the hood of your car, near the master cylinder. The reservoir is a plastic container with a lid that has a brake fluid level indicator on it.
2. Check the brake fluid level. The brake fluid level should be between the minimum and maximum marks on the indicator. If the level is low, you need to add more brake fluid.
3. Open the brake fluid reservoir. Remove the lid from the brake fluid reservoir.
4. Add brake fluid. Use a funnel to add brake fluid to the reservoir. Add enough brake fluid to bring the level up to the maximum mark.
5. Close the brake fluid reservoir. Put the lid back on the brake fluid reservoir and tighten it until it is snug.
6. Test the brakes. Pump the brake pedal several times to ensure the brakes are working properly.
