Don't know why it won't bleed but you might have better luck with the vacuum pump method. Get a Mity-vac or similar with brake bleed kit. Fill the master then draw a vacuum at the wheel cylinder until it runs clear. Make sure you don't run the master dry. You will prob have to stop (shut the bleeder) and refill the master once or twice unless you can get someone to refill it on the fly for you.
