vendo396 Dec 22nd, 99, 5:26 PM I have a 70 ss with a 402 with a big cam and get about 7 to 10 inches of vacuum at idle. The brake pedal gets real hard sometimes, do those brake cans you can buy for reserve vacuum work. al ------------------ Vendo396 68Malibu Blown 406 Dec 22nd, 99, 8:51 PM Yes. Larry Dec 23rd, 99, 4:41 AM You might consider a vacuum pump like that sold by Master Power brakes. I seen that if you know where to look in the boneyards that other late model cars (Citations, etc.) used them also. I installed a new last summer...it's a pleasure to not have to use both feet on the brake pedal after the first push. vendo396 Dec 23rd, 99, 3:23 PM What do you mean by pump? <BLOCKQUOTE>quote:</font><HR>Originally posted by Larry: You might consider a vacuum pump like that sold by Master Power brakes.

It's a vacuum pump, by which I mean an electric motor which draws a vacuuum...one end hooks up to the vac. can for the brakes, the other goes to a vac source on the the engine. If I remember correctly (which I don't) it kicks on at about 10 or 15 inches if vac and shuts somewhere around 20. I'd have to look that up to verify, but I'm pretty sure I'm in the ballpark. It's really quite slick, and no matter how little vac your super big overlap cam has, you'll always have vacuum for the brakes. I highly recommend it. Believe me, I've had plenty enough one good shot at the brakes to appreciate this thing. vendo396 Dec 23rd, 99, 6:12 PM I was just talking to a guy who has the same thing, are they about $100.00. al <BLOCKQUOTE>quote:</font><HR>Originally posted by Larry: What do you mean, by "what do you mean"?
