Can you top up brake fluid yourself?
If you have a low brake fluid level, topping up is really simple. Park your vehicle on a flat surface. Clean the brake fluid reservoir cap if it’s dirty, so no debris falls into the reservoir. Slowly and carefully add brake fluid to the reservoir until the level reaches the maximum fill marker.

Should the brake fluid reservoir be full?
The reservoir should not be filled past this line. As you drive your car and apply your brakes, your brake system heats up, including your brake fluid. As brake fluid heats up, it expands. The path of least resistance leads the brake fluid to expand back into the master cylinder reservoir.
