I actually tried the unit from harbor freight last year, couldn't get it to work.
I get piston syringes free from work and I've seen multiple guys on YouTube use them to reverse bleed so I will try the push pull method first. The first time I did it though I did make a mess. I think there is some sense in what designer is saying too regarding the mitty vac, it's constant suction and will be what I will try if the piston syringe doesn't work. You guys both have good points and obviously know a thing or to about the process. There's multiple ways to do a thing, just agree to disagree. You guys are obviously both good people because you've both taken the time to give your advice to a random guy like me on the internet and I appreciate it. I don't want this thread to turn into another axel grease thread, not taking shots at either of you guys here. Just chill out guys.
Thank you for your patience with this needless bickering.
While I have no experience with the Harbor Freight Tool, I can assure you,.. as do many tens of thousands of Mechanics, that the Mity Vac Tool works well Right Out Of The Box,...and,....is not anywhere's near as messy as is the Syringe Method is.
Do remember, that reverse bleed method will push the air up into the Banjo Fitting. And being a pressurized method, is more prone to leaking at the valve, even with Tape. The Tape tends to break down it's seal every time you turn the Bleeder Screw. So it's good to minimize Opening/Closing of it.
I find that the pulling the Fluid method better in that you are not fighting gravity by pushing the the Fluid Up. The Air will always rise, and thus the need to clear the Banjo Fitting will be there using either method.
