I personally don't carry brake fluid, but I am mindful of the action of the brake pedal. If it goes down more than it's supposed to, especially if it hits the stop, that generally indicates a problem. That happened to me a few weeks ago; the problem was leaky calipers. The brakes still worked, but as I was about to tow a trailer, I wasn't interested in taking chances.
A good way to test for brake system leaks is standing on the brake pedal with all possible strength with the engine running for power assist. If it sinks toward the floor at any speed, that indicates a leak. Immediate attention by a licensed mechanic is required.
There is likely an exception somewhere, but brake lines and seals generally don't cause trouble for the first ten years. All bets are off after that.
