If there are no leaks in system, then booster may be bad.
Remove MC and look for brake fluid in booster diaphram.
It is also VERY important to bench bleed MC before install, did you bench bleed it?

I did bleed master cylinder before installling. when I installed master cylinder did not see any brake fluid in booster diaphram.

If there are no leaks in system. Then you may have a bad MC. It happens.
The reason I mentioned the bench bleed is that if you install a MC dry and use pedal to pump up, you will ruin the piston seal in MC.
