As brake fluid bleeds out, regularly check the master cylinder to make sure it doesn’t bleed dry. Continue to add new brake fluid to the master cylinder. When you stop seeing bubbles and see the color of the brake fluid become clearer, you’ve bled most of the air and old fluid out of the system.

Why do brakes bleed?
Bleeding the brakes is an inevitable part of DIY automotive repairs. Air can enter the brake system during repairs, but the more common reason is far more insidious. Brake fluid is hygroscopic and readily absorbs water from the atmosphere. Water in the brake fluid lowers its boiling point. Heat boils the brake fluid, and the resulting steam leaves air in the lines. Brake fluid is incompressible while air is easily compressed and manifests as a spongy brake pedal or worse.

How does air affect brakes?from brakes-shop.com
When air (or vapor) becomes present within the lines, it creates inefficiencies within the system because, unlike liquid, air can be compressed. So when enough air fills the lines, input at the pedal merely causes the air to compress instead of creating pressure at the brake corners. In other words, when air is present within the system, the efficiency and effectiveness of the braking system is reduced. Usually, a small amount of air within the brake system will contribute to a "mushy" or "soft" pedal (since less energy is required to compress the air than is required to move fluid throughout the brake lines.) If enough air enters the brake system, it can result in complete brake failure.
Why does air enter brake lines?from brakes-shop.com
Technically, "air" only enters the lines if there is a compromise of the system's sealing (as when flex lines are removed or replaced), because when fluid boils, it will instead create "fluid vapor.". Vapor in the brake fluid, like air, will create an efficiency loss in the braking system.

Why do you need brake fluid?from brakes-shop.com
The role of the brake fluid within the braking system is to transfer the force from the master cylinder to the corners of the car… and a vital characteristic of brake fluid that allows it to perform its task properly is its ability to maintain a liquid state and resist compression. In order to keep the fluid in top condition, many enthusiasts have been taught to “bleed their brakes” but many have never stopped to ask the question “why?”
