Where exactly does the brake booster vacuum line hook up? I changed my brake pads and they are still pretty weak so I'm thinking that it may not be hooked up correctly. Any ideas?

 

There's a vac line that runs along the firewall for it. Not too many vac lines that big on these cars, should be hard to miss if it's there.

 

It's hooked up there but it is unhooked to the engine. I wasn't sure where it hooked up there.

 

If it's a true USA series four turbo engine, it goes as shown in the attached jpg. IF series five.............it does NOT go there.

 

Its a series 5 engine. Sorry I should have put that in the original post.

 

Where would it go on the series 5?

 

ON the rear end of the intake manifold. I don't own one and never seen one other than this site. I think SEARCH will turn up something if BRAKE BOOSTER FEED or BRAKE BOOSTER MANIFOLD words are entered. I think there are several pictures out there for series five turbo.
