If there's no leakage anywhere and you adjusted the booster pushrod properly-I will recheck the master cylinder though it's new could be leaking internally-

Thanks for the help, kind of what I thought the problem was. After posting this question, I went back and took the lines off at the master cylinder, and used a brake vacuum pump to test for leaks, no leaks, it held 15lbs steady.

Next question;
how do you check the master cylinder for internal leaks? Or do I just take it back and exchange it?

Thanks again for your help.
