Check the vacuum line to the brake booster, make sure there is vacuum to the booster.

Did this start when you installed the new master cylinder?

My first thought would be the booster to master cylinder rod is not in the right place.

Did you bench bleed it? I ask because i had the same problem with mine. The first problem was it was the wrong master cylinder i put on, The pedal would move and then go to a dead stop. Then got the right master and didn't bench bleed it??
