You just need 4-5 psi.  Be sure you have enough fluid in the bottle to finish the job. If you have to add more when you crack the cap you'll bubble air into the fluid remaining and will need to wait several hours or toss it. Don't use aerated fluid!

It's a great tool, and I have adapters for all my cars. Brake fluid should be changed every two years, and this makes it pretty easy.

I've cut the hose on mine and put in a coupler. That way I can use it to pressurize the cooling system for leak checks @ 14psi.

Subject: Questions about brake bleeding

Hi van people,

I have two questions related to bleeding:

1. I have a new Motive Power Bleeder on its way to me (yay!) For those of
you who use these, what PSI do you use on the van?

2. What order do you bleed? I have a manual so I'll be bleeding the clutch
slave as well.

Many thanks!

Joe
