You'll have to disconnect the brake lines from the calipers before removing them since they're metal tubes, not hoses. Depending on whether you mind a little brake fluid on the floor, you can either place a large pan under the wheel assembly as you do it, or attach a rubber hose to the bleeder valve and stick the other end in a can, or bottle to catch the fluid.
The way I've done it is to have a friend get in the car to pump the brake pedal. He'll call "open" when he's ready to pump the brake. I'll then turn the bleeder fitting counter-clockwise about 1/2 turn, call back "open" and he pumps the brake pedal. As he gets toward the bottom of the stroke he'll call "close" and I'll shut the bleeder valve. That process continues until there are no air bubbles or the new fluid starts coming through. It will be more clear than the old stuff.
If you're just bleeding the brakes to remove air, then stop the process when there are no more air bubbles.
If you're changing out the fluid, I'd get a turkey baster and suck as much of the old brake fluid out of the master cylinder as I can before doing the process above and then fill the resevoir with new fluid, then start the bleeding/purging process. Do it for each wheel until the old, yellowish fluid in the lines is purged and the new fluid comes out clear.
Make sure you check the master cylinder from time to time to avoid running out of fluid. You don't want to pump air into the lines. Also, do not turn the ignition on during this process. keep it off, or on accessory. It's my understanding that the brake system will throw a code if you try to do this with the ignition in the on position -requiring the code to be cleared with a Tech II.
