So, today I went and bled all four corners.

As always, I used my pressure bleeder, with ~8 PSI pressure. Bled all 4 corners went up to check pedal pressure and notices a BIG pool of brake fluid on the cab floor.

Couple questions.
1) I assume this means the master is shot and has to be replaced or rebuilt. Is that correct? Is there some other way that brake fluid could have gotten into the cab?

2) this was a new cylinder. Zero miles, though I did install it last year. I have no clue where the NAPA recipt is. Should I even try to take it back, or should I just pony up for a new one?
