Can't bleed Left Front Brake caliper...

My '97 Voyager has had two master cylinders to attempt to fix a low pedal. Yesterday I successfully bled all brakes except the left front. I couldn't even get fluid until I put a vacume bleeder on it. Then I could do a normal bleed but it keeps pumping air. There are no visible leaks. I don't think the master is defective since the other brakes bleed just fine. It has an ABS system which may or may not be related... Any suggestions???

This is a VERY strange problem... I Still get a perfect bleed on all brakes but the Left Front. No leaks but lots of air... Any ideas???

After 3 new master cylenders, a new power booster, and 2 front calipers, we finally found the solution. Had to replace the ABS controler ($100 used + $165 for a dealer to install it). Things are (so far) Great.
