That is known as reverse bleeding. It really helped me on my 97. I rigged togetehr a setup using a clean glass jar, some clear hose, and the air compressor with a regulator to only push about 3-5 psi. Fill it up with brake fluid, connect the hose to the beeder and open it a little, apply pressure to the jar, and it pushes fluid toward the master. Makes sense to me as this way you can push the bubbles up, rather than trying to push them down. Before doing this, bleed the normal way first to make sure you are only pushing clean fluid toward the master.
