Just converted to CR style brake routing. While I had the old line off my wife helped out by pumping the brake lever to, "get all of the stinky old oil out"....Besides making a mess, air was sucked into the master cylinder. I bought a vacuum pump bleeding tool and sucked about a qt of fluid through the bleed screw, but the lever still feels spongy on test ride. Is there a way to "bench bleed" the master cylinder? Any help would be great....getting a new wife has already been considered.
