OK my brakes are really week, they go all the way down to the floor then work after a pump or two. iv bleed the lines starting from left front ending with right rear so im sure if there's any air in the lines i got them out. only thing i can think of that's making this happen is the booster vacume.
i have a J-Spek so the connections where not the same a the A-Spek but i ran the line from the booster to the top nipple on the top of the UIM. when i pulled it off and tested it it didnt seem like there was any kinda of vacume coming from this nipple.

so i guess im asking where's the best place to hook the brake booster vacume line up to?

 

I experience the same thing but not to the same extent. For the vacume connection for the Brake booster I used the same vacume line the J-spec had for the brake booster..

Maybe you hooked up the line to the top of the TB (coolant line?) You can hook up the brake booster anywhere

 

on my jspec s5, i used the nipple on the top of the lower intake manifold, pretty sure thats what it used stock.

 

these links are pics of where i have it hooked up..

wrong spot. The brake booster line comes out of the LIM right next to the ACV.

 

could you point to me where i should have it connected? heres a pic of the passenger side intake

 

I ran into this to with my jspec. Here is a pic of mine and it works fine.

TMIC? what does that stand for?

 

Oh nvm you ment the line that went to the side of the stock IC. What was that line for anyways?

 

That bolt next to the blue loop of silicon hose is where it usually goes (it's a banjo bolt)

 

our UIM are not the same is there any place you see in my picture where i could hook this up 2?

 

see that bolt that is at the upper left edge of your LIM? it's just right of that blue vaccum hiose you got... Find the thread pitch and install a fitting that you can use for the booster. That's where your brake booster line should be....

 

I didn't have a spot on my manifolds. I had to do this....
