What am i doing wrong. brake lines
just put a new set of ss brake lines, used a brake pressure bleeder to get the air out of the lines but no air. i filled up a 12oz bottle and had no air bubbles on all 4 sides. but when i go to push the brake peddle in it is spongy and still filled with air.
what am i doing wrong?

The pressure bleeders don't always do a very good job in getting all of the air out of the lines. And 12 ounces isn't enough to flush the system, should take a quart/liter. Get a friend to help you and do it the old fashioned way, you'll move a lot more fluid, which will help carry the air with the fluid.
Also, there are two bleeders on each caliper. The first time I did my brakes on this car, I did not realize this, as the other calipers I had had before were not like that (including other 4 piston ones). Long shot you missed that, but if you are new to it, you might have.

Agreed with 67King.
I use my pressure bleeder to get the initial bleed done, but I always go back to the old style "pump the pedal" method for the final bleed. And I always get a little air out at the end too.
