brake issue

1937 Packard 120c
i am not a mechanic, not even a shade tree one... so
i replaced my master cylinder, which was surprisingly easy and straight forward. bled lines in correct order and took out today for test drive. very little play in brake compared to before. Manual says 1/4-1/2" play, which i have. but is very tight compared to loosy goosey brake action before.
PROBLEM:
at low speed, applied brakes slowly and not only stopped quickly but VERY noisily and scary sounding! never happened before. so is there still air in the lines or ??
thanks
