Reverse bleeding pushes all the debris from the wheel cylinder up into the master cylinder. This will be trouble in the future..
 
The two person method works well but you must not wait long between the pumping action at the master cylinder as any bubble
in a hose will travel beyond the prior pumping action rendering the bleed useless.
 
The best is the pressure bleed. A small pot is filled with brake fluid and pressurized to 20 psi. The pot is connected to the
master cylinder reservoir. When the bleeder valve is opened at the wheel cylinder, the fluid is pushed out at a fast rate allowing
all debris and air to escape. This is the de-facto standard in the auto industry and commercial aircraft.

On a car I was taught these steps.  It takes two people.  I cant tell you why this might work, I dont understand the workings of the brake cylinders.   But this method would push the bubble in the opposite direction and involves "closing" and pressurizing the brakes.

1: One person pumps the brakes to pressurize the system.  
2: With the brakes held, the second person opens the zerk and relieves the pressure, then immediately closes the zerk.
3: Release the brakes and add more fluid ass necessary
4: Repeat until the bubble  is gone.

The last time I bled the brakes I pumped about three cans of fluid through the bottom-up method of bleeding brakes, sure that I had solved the problem--didn't. 
Is there another method to attack this?
