Hey, I just got my new carburetor on and everything is working fine except for the power brakes. I had to hook the powerbrake booster vacuum line and a (pcv?) hose from the valve cover into a t T-fitting in the back of the carburetor. There was only one outlet, but I needed to plug in two hoses, so I got a T and hooked them both in. Now when I use the brakes I have to almost stand on them to get the car to stop. I never had to do this before. What is can I do to fix this?

Thanks,

Samuel

I know I suggested the fitting for the manifold. If your not married to the pvc valve. you can always just use a breather in the valve cover instead. Or break down and find another throat plate for the carb to sit on that has the port on it.

As a last resort, you can get a vacuum booster ( I think the name is incorrect) that helps build more vacuum for the brakes.

Seems like no help for your new carb setup, but is all I can offer.

what does the pvc do? Does it matter if I just put a breather cap on it?
Thanks,

The setup is mainly there to allow the intake system to pully floating impurities and gasses out of the crank case. in MHO it's not needed. I've been running my small blocks for the past 25 years without one and only using the breathers. They will still allow the crank to drain off any pressure that builds within it. Depending on the usage, oil may or may not collect around it on the valve covers. Some have experienced this, I've not so far. For an idea of the difference in appearance, go to the address in my sig and look up the engine bay. I typically only wipe down the valve covers and filter cover because of finger prints and dust. The motor looks like it does in the pic 95% of the time.

Re: Power brakes not working

Hey Samuel, there is always Hydro-boost. I'm am going to order mine today. You will never have to worry about not having enough vacuum if you decide to use a high lift cam. The Hydro-boost runs off your p/s system. Plus, it gives you two to three times the clamping force compared to a vacuum booster. Also, the best thing of all, it looks awesome under the hood. Good luck and let us know how things work out.
