Technical Vacuum Question 350 Chevy

Thanks was wondering about the valve on the canister and then going to one on the booster, will do some re-hosing tomorrow and see what happens

 

When I did the front disc brakes from Speedway, I also got the pedal ***embly and booster/dual master from what the tec told me. Going to try redoing the hose hook up tomorrow and check vacuum at the manifold, if that doesn't have some results I look into a bigger booster.

 

Just did some rethinking, the hose from the manifold going to the canister is connected with a open L fitting so there would be vacuum going in the canister. The hose coming out of the canister going to the booster has the valve in it were it connects to the canister.

 

Just did some more research hose from manifold connects to valve connect on canister, then open L fitting on canister goes to valve on booster. Is this what your referring to?

 

Yes. The hose connection on the valve is the vacuum side. That should go to the manifold.

 

I like big stock boosters and I get them with a matching master if possible. The 7" ones that one size doesn't fit all are problematic. Have you hung a vacuum gauge on it yet? I'd be curious what you have at idle.

 

OK Thanks

 

Going to put a gauge on this morning and go from there

 

Find out what the vacuum is at idle.. Under 18" your not going to have any booster work right.

 

What kind of distributor cap is that?

Hei from Summit

 

(Up date) Put the gauge on the manifold , slight wiggle up and down 14 to 15" with motor at 140 degrees. Going to re-route my hoses right and see what the brakes do.

 

Up date run the vacuum straight from the manifold to the booster, big difference Got power brake now!

 

Nice going. I side-stepped the power brake option on my car due to the cam and fitting the booster in the allotted space. It stops great with manual brakes.

 

Thanks everyone for the help, sure made it go smooth!

 

simple is best!
