I have a 2000 Road King that I recently took off a aftermarket chrome master cyclinder and replaced with oem. Bought a vacuum bleeder from harbor frieght. Went to flush and bleed brakes. Nothing was coming out when I released the bleeder screw. Some fluid would come out from the bottom of the screw but nothing through the vacuum. Lever still spongy. Haven't tried reverse bleeding because old fluid is still in the lines. Any help on how to flush and get pressure back on the lever. Really don't want to take it to a dealer and pay the 89 dollar labor rate for something I can do in my garage. Thanks.
