Thread: Vacuum for Power Brakes!

Tweet

"relocate my vacuum takeoff at the carb base and go from there."
Not thinking that will change anything, the vac will be the same. Before you do any plumbing check both ports with a gage.

Have read when you have the time, this will clear the air and explain everthing:
Master Power Brakes - Reference/FAQs: Power Boosters

I' ve been going over my brake system and this is what I have now:
The biggest problem I had was not enough throw from the pedal pivot to the master cylinder rod. I extended the throw but lost some leverage up top! But before I was not moving the MC piston enough. Now If I nail the brakes it will lockup and slide, a vast improvement!
I have found that my engine makes 9" of vac at idle, bring it up to 1200 rpm, it will produce 20". So now I have to decide how I want to go about producing vacuum when I'm in traffic and can't produce the RPMs' to bring up the vacuum.
At least now I know I can stop but sometimes it just takes more pedal pressure!
It's probably time to buy a pump, Summit has a couple self contained units made by CVR
that look like an easy install!
