Looking for some info on how to bleed brakes simply using gravity. Never done it this way. I think I may still have some air in my system. I have bled the brakes twice, once by reverse bleeding and secondly the traditional way by pumping the brakes and opening up the bleeders one at a time.
With the gravity system...how do you go about this?
Do you open one bleeder at a time or all at once? Do you using a specific pattern...which caliper do you start and end with? How much fluid do you expect to use with this method?
Reference: 61 Galaxie, 78 Cougar front discs, 83 Lincoln rear discs, 94 1500 Chev truck master cylinder and Astrovan hydroboost.

Never done it, but I would think that you would treat it like using a pump, or the old pump the pedal method by starting with the one farthest from the master cylinder and working to the closest.

Works really well to change brake fluid. It will help to remove some air but doesn't work very well to remove trapped air. Search for a video, lots of them on the web.

Used to use the gravity method while I was still working. Works good. I would do 1 wheel at a time. After I assembled the wheel cylinder, brake shoes and installed the drum I would leave the bleeder open and move to the next wheel. When I saw the bleeder start dripping I would close it off. Of course you have to keep the master cylinder full. After the last wheel was finished I would bleed the system the conventional way with a helper pumping the pedal.
