Alternatively, you can bleed the master reservoir down, fill it up with fresh fluid, and never add fluid to the bleeder tank. That way, if your connection blows, you won't have brake fluid flying all over the place. Using this method, you may have to stop once, fill the master a bit with some more fluid, and then repressurize and continue the bleed.
