    Brake booster aint boostin shit!

    Aright so when I brake, my pedal fades until it becomes a "hard pedal". While I'm on the brakes it hisses like a vacuum leak. So, I had my sister pump the brakes (while the car was running). and I listened under the hood for the source of the leak. Turns out it was from my booster check valve. I replaced that...still hard pedal. I checked the hoses, and they were all cracked and shit where they met the check valve, so I replaced those. Mind you, I just went to the nearest auto store and bought 11/32" vacuum line and cut it to length. I didn't buy the direct replacement part from the dealer...just cuz. I didn't think it'd make a difference. But needless to say, it's still hard! haha what the hell's the problem?

        I think it's an easy fix , you just need a manual and probably a help from a friend to get you calm when you panic. Lol j/k buddy.

          Any chance the vac hose you bought just isnt strong enough? It may be collapsing if its not the right size or whatever, iirc the stock hose is pretty stout.

            That does make sense Rosko. How would I figure that out? Just look at the hose an feel it when someone hits the brakes?

              No as soon as the car is started vaccum will be applied to that hose so if its gonna collapse it should do it right away. Dunno if thats it or not but I used some cheap hose for a PCV line once and it did just that.
