Pumping up the pedal should be done very gently. If you are too agressive you will break up all of the air into tiny bubbles. I usually have the wrench and my wife in the car. I have a clear platic tube I attach to the bleeder. My wife keeps light but constant pressure on the pedal all of the time. Simply hold light pressure and open the bleeder. When the pedal hits the floor close the bleeder. let it up, repeat. Continue until no bubbles. Check the master often! Drop a couple extra bucks for the good stuff too! Have heard dot 3 holds moisture. Again work farthest to closest.
Just wondering the condition of the hoses? I would suggest you have somone hold heavy pressure on the pedal while inspecting all rubber hoses. Think you said all the lines are new? If not follow all of them looking for leaks. No rubber splices no compression fittings, just double flares and metal.
Sorry Not Vlkki but I did teach brakes for a short time. I sure do like the color of her car! Along with my wife, neighbors, and a few friends, Vikki's pics talked me out of the blue.
