2 things come to mind, further brake adjustment needed, or still air in the system. Having said that, some years back, when we had the shop open, I went thru 4 Master Cyl's from our supplier until I got a good one. He simply shrugged his shoulders & said they must have had a bad batch come in. 3 days of labor down the drain.
