Is this thing really nessessary? I keep getting vaccume leaks from this point in the line and would like to just replace the entire line running from my brake booster to the intake manifold. I'd rather just use one line running across but i wasnt sure if the lines coming off the brake booster and the intake mani were the same size, so I ask again, is the check valve needed?

W/O it you won't have a Power brakes and would make your Brake Booster useless. Have you Replaced both the Line and Valve Already?

Thanks for the input. I haven't replaced the line yet, just put a new clamp on. If that doesn't fix it, I'll replace the line. Mainly I just wanted to know what purpose the check valve served.

It'll hold the Vacuum in the Booster so that you have Vacuum in the booster when you need it. If not you would have Positive pressure in your booster which would pretty much eliminate your brakes lol.

Doubly true if you're running boosted, but just as valid if you're NA.

Seems you've not noticed the different brake modulation needed if you clutch in and floor it in the middle of a breaking event.
