Spongy brake issue.

Ok lately my brakes have been very 'inconsistant'. Sometimes when I press on them they are firm and stop very effectively, but more and more I'll push them and they are very spongy. So spongy that I, no joke, have to push them to the floor before they grab enough to slow the car. Pumping them helps sometimes, but not usually. I have also felt them give a few times when I was already pressing them, the 'firm' brake ped will spontaneously sink down closer to the floor and become the 'spongy' brake ped. The brake fluid level is fine. I was thinking it could be the master cyl. Any suggestions?

Could possibly be the fact that there is air in the system. Did this just happen out of the blue or is it a problem after a rebuilt? If it was a rebuild they may have left air in the system( it was not fully bled ).

Also could be a loose break line? Too much fluid getting in the drum, if you have to stand on the breaks to make the car stop check into this.

have u ever flushed the system? if the fluid is new, then u probably need a new master
have u done any work to the brakes recently? like calipers or cylinders?
might have air in the systerm
