My old boss sent me this link, he uses it on his Viper to bleed the brakes.

Basically it's a presurized tank of new brake fluid that is attached to the reservoir. As you crack open the bleeder screw, new fluid is forced into the system at the top, pushing old fluid out of the calipers. So no pumping, no helpers needed, no refilling the reservoir. Flush the brakes in about 10 minutes by yourself!
The "Import Power Bleeder" is $65 and will work on all Subarus, and most other imports. Or for $100 you can get the larger 4qt model with every friggen attachment and be able to bleed anything.
