Find a bleeder bottle and tube. These are less than $5. I need to empty this bottle:
Loosen the bleeder valve on the wheel cylinder just enough to let the brake fluid go through, and place the end of the tube to the bleeder bottle over the end of the valve:
The bottle can hang over the side of the tire:
I flushed out most of the brake fluid as it was old and dirty. Just make sure the tube is connected before you push the brake pedal, and that all of the other bleeder valves are closed. You don't want air to get back in to the lines. Also, make sure that you don't let the fluid run out in the master cylinder:
Here, not only are there air bubbles, but the brake fluid is still pretty brown:
After the fluid looks fresh and clean, and there are no more air bubbles, twist the plastic tubing to close the bleeder valve as much as possible. Reach up and twist the valve with your fingers and tighten as you can with a wrench before removing the hose. Tighten with a wrench some more after the hose is off. Don't torque it down too hard or you will break off the bleeder valve, or it will break off next time you try to loosen it. I was able to get fairly firm braking with this method, not spongy at all.
