How does the brake bleed order work in a Subaru?

Subaru's use cross-redundant braking, so if the drivers front fails, you have the passenger front and driver rear still operational. I believe the "bleed order" comes from how the ABS unit mixes fluid.

When do you have to bleed the brake systems?

You must bleed the brake systems when air bubbles get into the system during a repair or replacement task. An anti-lock braking system (ABS) is less tolerant of air bubbles and polluted fluid than a non-ABS system. An ABS hydraulic pump uses thousands of psi to push brake fluid through tiny valves.

Do you use a vacuum on the brake bleeder?

Yes a vacuum device on the brake bleeder is very effective, esp if you put some silicone grease on the bleeder threads to help keep it from sucking in air. This way you can do it yourself without having to open and close the bleeder 100 times.
