Default brake pressure problem on 04 dak

So if I press the pedal hard the pedal is firm as it should be. If I slowly press it it will go all the way to the floor. Problem started last week and progressively got worse. Any help would be great.

Sounds like the cups in the master cylinder aren't sealing well anymore if you ask me. When you hit the pedal hard the fluid doesn't have time to leak around them yet, so the pedal is firm, but if you push it slowly it is letting the fluid leak around the cups.
