If the brake lines & master cylinder are empty, I add the brake fluid from the bottom up, using a CLEAN pump-oil can & a length of clear vinyl tubing of the proper size to fit the bleeder valves. Start with the right rear since its the farthest from the master cyl. Then, the driver side rear, followed by the rt. front & lastly the left front. Pump in just enough fluid until all the air is expelled from the line. Have a helper watch the master cyl. reservoir so they can tell you when to stop pumping. Then repeat the process for the other 3 wheels. Lastly top off the brake fluid to the proper level.
This method works great since air bubbles tend to rise naturally, instead of trying to force them downward and out thru the bleeder valves.
