Recently replaced both master cylinders and slave cylinder and now must bleed the system. I removed as much of the old fluid from the calipers and wheel cylinders as possible with a Mitivac and blew the lines out with compressed air. Starting with the rear driver side wheel cylinder, will I be able to draw fluid from the reservoir with the Mitivac? Is it wise to fill the master cylinders with fluid before attaching the lines? Looking for the most effective way to fill the system assuming it is completely empty.
