I'm not familiar with that specific system but it sounds like what happens on GM front-wheel-drive cars when you press the brake pedal too far during pedal-bleeding. A valve in the master cylinder trips and blocks the two ports that weren't building up as much pressure, as in when there's a leak. The only way I ever found to reset that valve was to give a quick short burst of compressed air into one of the open bleeder screws at a wheel that won't bleed, then let it gravity-bleed. If you have to irritate the brake pedal a little by hand to get the flow started, just press it an inch or two a few times.
