When you say the new brakes, what was done? If it was only brake pads or shoes, the system wouldn't have been opened.
Next, if you pump the brakes, does the brake pedal pump up? Keep in mind, the brake system is a sealed system and no air should be able to get into it. If there are no leaks and the fluid doesn't change level, either the bleeding process is not being followed, the master cylinder is bad, someone reversed the brake caliper side causing the bleeder to be on the bottom, or something is bad and allowing fluid to enter.
Take a look through this link:
Also, here is a link that explains how to bleed them. Let me know if this is how you did it.
Let me know exactly what was replaced, the symptoms you have, and if the above listed links are helpful.
I will watch for your reply
