How did you bleed them? The procedure for the ABS brakes is a bit different than it is for normal brakes, particularly in the rear. For the rears, you do NOT pump the pedal up & down & open & close the bleeder. You have a helper turn the ignition to "on", but do not start the car. Let the dash lights for the brakes go out. Then have them push on the brake pedal , and when they do that, you open the bleeder screw, and close it when the fluid flows clear. Then they can remove their foot from the pedal. Do this ONCE for each rear.
The rear brakes are activated solely by the hydraulic pressure created by the pump. All you do in the MC when you press on the pedal is open a valve that supplies both rears with pump pressure.
Remember, too that you have a LOT more plumbing to go through up front, so while it may have looked clear, there may still be air trapped in the innards of the ABS system. As I recall, the Saab workshop manual says to drain about a half liter of fluid through the left front first, then go on to the right front for about a quarter liter, and do the rears last (about 0.1l each).
