I'm confident that you bench bled the master cylinder before you installed it.
follow the bleeding sequence. Start with RR(1) and finish with RR(1)
(Do it in old fashion way,by having someone pumping on the brake pedal.Start with #1 .when brake fluid coming out is clean and without bubbles, ask the helper to hold the pedal down while you screw back the bleeder screw.Make sure the brake reservoir is always full, do not let it empty and let air in the master cylinder, then go the #2 and do the same.)
