If the brake fluid is clear and no air bubbles are in the hose, then no air is in that brake line and the valve can be closed. Pinch the bottom of the hose tightly and remove it from the bleeder valve. Lift the hose up to let the fluid drain back into the bottle. After bleeding the brakes for a wheel, check the fluid level in the master cylinder and add fluid if needed.
The procedure is complete when all of the air is out of the system and the brake pedal depresses firmly. To prevent pollution, dispose leftover brake fluid safely. Brake fluid and other various automotive hazardous waste can usually be returned to your local auto parts store. Local junkyards and dumps may also have hazardous waste disposal.

Bleeder bottle with a fuel hose. Some consider the pressure tank brake bleeder the very best there is. When you absolutely, positively want to push every last molecule of air and rotten brake fluid out of the system, accept no substitutes. The Motive unit shown here is one of many, but the concept is the same.
Pressure check the tank-to-master-cylinder connection for leaks with air only, depressurize, fill the tank with brake fluid, pressurize, and take a leisurely walk around the car cracking bleed screws with a wrench and catch can. In this case, the pressure bleeder sorted out the rear ABS brake modulator under the Starion hood like a champ. All of these methods work.

Matthew Fink. Instead of against your rim, these calipers compress against the brake rotors which are connected with your wheel. The friction between the rotor and the brake pads brings the rotor, and in turn the wheel and your car, to a stop. If you think about the braking process, the fluid is one of the crucial parts. This fluid directly connects your input on the brake pedal to the compression of the calipers.
Without the fluid, there will be no brake caliper movement and no stopping. Even if there is fluid in the lines, that fluid can sometimes contain pockets of air.
These pockets of air will be able to be compressed. This can lead to a spongy brake pedal. If a great amount of air is in the brake lines, it can even prevent you from stopping at all! This is why bleeding the brake system is so important.
Replacing the old fluid with fresh fluid is also a necessary maintenance task to ensure that the hydraulic brake continues to function properly. The container is easy enough to make on your own.
This can be done with something as simple as a 20oz soda bottle shown below. Step two starts with filling your brake fluid reservoir completely with fresh brake fluid. Make sure no debris gets into the system when taking the cap off.
