Your master cylinder might not being holding pressure.

 

The brakes are vacuum-assisted power brakes, but the vacuum assist doesn't come from a vacuum-pump, it comes from the vacuum created by the engine (Vacuum in Intake manifold)...
So, if you're positive that the system is free of air, the reservoir is full, and you don't see any leaks, then chances are the brake booster is not getting any, or enough vacuum due to a leak somewhere.
Check your vacuum lines and seal around the brake booster.

Good luck!
