I had the same problem with the HF version of the same system.

Assuming it was air getting sucked in though the sides/threads of the bleed screws, I placed the suction tube going straight up from the bleed screws (for example, threading the bleed tube through the front coil spring to hold it vertically above the bleed screw without me having to hold it), turned off suction, and let the fluid fill the tube above the bleed screw. The bubbles stopped, and the vertical clear tube filled with pure brake fluid (similar to watching a carbonated beverage 'settle' when you pour it too fast into a cup). Tightened the bleed screw, and success.

EDIT- as long as the master cylinder reservoir stays pretty full, no air should have gotten into the ABS system, so don't worry about that quite yet.

Good luck
