I follow this guy's youtube channel because he has so much cool footage of his S2000 at nearly all the tracks in Japan. One of his more recent uploads is this video of him using engine vacuum to bleed his brakes. It looks like an interesting idea, but the short bit of video doesn't really show all of the air getting out. I am assuming with the caliper swap that there would be a lot of air, and the video isn't long enough to show clean fluid coming out yet.

Check it out...

kkkk circuit Brake Bleed

 

Brake bleeding this way would be nice and time saving!

 

They make bleeders that hook up to air compressors plus have a reservoir for holding old fluid. I still like to do a manual bleed after but these work well to push alot of fluid through in a short time.

 

That's a lot of crap in the way just to do something simple.

 

same thing as using a hand held vacuum pump, same principle.

 

I actually did this on my truck once. I used a glass jar with npt fittings screwed into the lid. It worked well, however I almost killed myself with the fumes from the engine running. Not my brightest moment.

 

looks cool but not mistake free. Id like gravity the best, speed bleeders are nice too
