Re: Power Brakes/Manual Brakes

[Dan McCormack <mcwheels@xxxxxxxxxxxxxx>]

There's another reason I can think of for converting to manual brakes 
especially if you're building a radical engine and that's with a radical cam 
you will not have enough vacuum to run the booster unless you install an 
auxiliary vacuum pump.

Then there's my friend with the 67 Charger race car. A few years ago he blew 
the engine just as he was crossing the finish line at about
130 mph. Not only did the car fill up with smoke so he couldn't see when the 
engine blew he lost all the vacuum to his power brake booster. He's lucky to 
be alive as he wound up out in the woods somewhere before he could get the 
car stopped. Needless to say he now runs manual brakes on it.
