'87 C4 Brake Problem

I have been having problems with my brakes & found that it was a leaking master cylinder. I replaced the master cylinder & bled everything but now it ewes that the system doesn't hold pressure. When I press the brakes it feels like it has pressure but as I hold the pedal, the pressure seems to dissipate & the pedal goes to the floor. I haven't found any other leaks after I replaced the bad master cylinder. Any ideas?

You think the new master cylinder is bad? It was a remanufactured one, the only one I could find locally.

Had to take another crap shoot, I couldn't find a new master cylinder. I found one more rebuilt locally & it worked. Thanks.
