Can also be done by yourself if you can't find someone to help. Get yourself a clear jar, I use a mayonaise jar. Fill it about 1 or 2 inches high with clean brake fluid and attach your bleeder hose to the rim of the jar so the end of the hose is submersed in the brake fluid. Open bleeder valve, and commence to pumping the brake pedal 3 or 4 times. Stop and check the level in the master cylinder, and top it off. Then back to pumping the pedal another 3 or 4 times. Eventually you'll see dirty fluid flowing into the jar, then clean fluid with bubbles, then just clean brake fluid without bubbles. Remember to stop and top off the master cylinder, you don't want to bleed it dry and create a whole 'nuther set of problems. When it's finally clean, go back and close the bleeder valve. This method can be used to bleed all 4 wheels as you can see the jar from the driver's side while depressing the brake pedal by hand and peering underneath the vehicle to see when the air bubbles have stopped. Just remember not to bleed the master cylinder dry, and don't stop bleeding the wheel until it flows consistently with no air bubbles.
