brake fluid leak after master cyl.

2000 3.3 liter
i just replaced my brake master cylinder and i have fluid leaking and dripping
off of the bottom of the master cyl. I have shined a very bright light while someone pushes brakes and i can't figure out where it is coming from. i am wondering if i got a bad master cylinder. it is not leaking into the vacuum booster. and it is definitely not leaking at the brake lines. anyone seen this

did you check where the resivoir meets the master cylinder? those gaskets can leak and the resivoir itself could be cracked.

did not think about a cracked reservoir since it was new.
i'll check it out
thanks
