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!Last edited by curmudgeon; 10-28-2012 at 07:23 PM.
