Has anyone here ever used a Leed Brakes "bandit" vacuum pump to supply the power booster?
My current setup is working and I want to improve my stopping ability. My 440 has a 484/284 cam with low vacuum. I run a line from the intake manifold to a Summitt vacuum can with a check valve and then to the bendix booster. The master is 1-1/8" bore and I have Cordoba 11-3/4" rotors with slider calipers out front, drums on the rear. The breaks grab nicely and consistantley but are short of locking up. I want to know if adding a vacuum pump to supply the can with more vacuum will improve the brakes so they will grab easy and lock up when I want them too. The breaks are working correctly and have no air in the system. I am just looking to see if anyone has used a vacuum pump and if it gave an advantage over the vacuum can alone. Without the can I could not use the power booster, with it, it has worked fine but i know it can be better.
Thanks for any info. I have not performed a vacuum test at the booster yet but I will when I get a chance. I will supply that info if needed. The can has a vacuum gauge on it and it usually rests between 15-18 but I can not read it when it at idle in gear.
