I used the Mityvac recently to, pretty straight forward.

 

I found the Motion Pro easy to use. Now I've got new lines. Will this prime them?

 

Just checked their website, which says it will not bleed air from a dry system.

 

Bleed kits are for cars, (unless you have someone pumping the brakes that's telepathic). Clean glass coffee jar & clear plastic tube, is all you need.

 

if you're swapping ss lines or something...where you will need to get air into the system, will definitely have to go with a mity vac...or else you'll be pumping 20000 times to build enough pressure to prime the lines. then another 20000 to get all the bubbles out.
