Re: Disc Brake Upgrade Reference Thread

The way I understand it is smaller diameter vac boosters = less overall vacuum accummulation = less overall assist. So, w/a smaller diameter booster, you'd still have more stopping pressure/force available vs other alternatives but it wouldn't be the most. It would prob read something like this.....

*Effective brake pressure/force exerted per ft/lbs of effort applied lowest to highest
Manual drum brakes
Power drum brakes
Manual disc brakes
Power disc w/small single diaphragm booster
Power disc w/small dbl diaphragm booster
Power disc w/Lg. single
Power disc w/Lg. dbl
Hydo-boost

*This is a generalization. Research each option for accurate factual data.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
