Best Method to clean open brake lines

[dmorgan]

On my 1994 Mercedes E320 wagon, I removed the abs/asr hydraulic pump motor. I am replacing the abs/asr hydraulic pump because I believed the pump motor is worn out. All of the brakes lines are open meaning all four brake lines that are unscrewed at the calipers. I want to clean all open brake lines to make sure all of the fluid, gunk, dirt, etc., clean and free air flowing before I install the replacement abs/asr hydraulic pump motor and putting in brake fluid. I am not sure as to how to go about cleaning open brake lines.

However, I did saw a video showing this particular method of cleaning brake lines: https://www.youtube.com/watch?v=3swnBRpneUQ

Is that an effective way to clean the open brake lines? Other options I researched so far is using brake cleaner inside the brake line and blow through the brake lines using an air compressor, vacuum pump or other means. Will a brake breeder kit I have will do the same thing? How about putting a thin wire inside the brake lines like a roto rooter type thing? Have anyone done this and if so what methods that would work the best? Any comments, feedback, advice is greatly appreciated.
