No matter the system, all brakes (or any hydraulic systems) have to be bled from the very highest spot. That's for the obvious reason that air bubbles rise to the top of the liquids they're in. I can't speak for your specific brakes, but in many cases, I'll bleed systems by oily cracking the plug at the top and pressurizing the system forcing air out until I see fluid weep out.

Odds are you can bleed your brakes in a similar manner, Don't remove the plug, but crack it open so air or brake fluid can weep out. Squeeze the lever to pressurize the line, and when the air stops and fluid appears, stop and plug. Note that in some systems the plug needs to be closed before the pressure is taken off the lever, or it may draw some air back in.
