Brake booster vacuum check before it's on the car

[70charginglizard]

Is there a way to check a new power brake booster unit for vacuum before you install it on the car?

I've tried to seach for a proceedure on this in here but cant seem to find anything on this.

A friend of mine is asking so I told him I'd see in anyone in here had anything on it.

Let me know ok?

Thanks

Can't you hook it up to a cars vacuum with a extra hose and test it that way?

Use a hand held vaccum pump, like whats used for bledding brakes. You can buy these kits cheap and they come in handy. Autozone,pepboys etc.
