I noticed my breaks on my van were getting loose. Then one day they went out. I mean pedal all the way to the floor and nothing. There was no break fluid in there so I had some put in, still nothing. I had the breaks bled all way around, still nothing. I then had a naster cylinder put on and still nothing. I don't know what's wrong...

Tried checking the o2 sensor, fuel pump, fuel filter, fuel injections system, did an oil change.
