Thanks, all this info is helpful. Like I said originally, this happened immediately after I depressed my pedal as hard as I could. When I did this, I pushed the pedal as hard as I could and at this time my brakes were fine and the pedal did not go to the floor, but after a few seconds of this pressure something gave and my pedal went to the floor and ever since it has been spongy and will travel to the floor if I push hard enough. My brakes cant even lock up anymore so my abs wont kick in when it needs to. This sort of makes me think its my master cylinder now, because if my brakes aren't locking up this probably means there isn't enough pressure in my lines. Ill try the bench test and go from there. Thanks.
