Brakes Power/Manual?

[ccracin]

Well, I'm still designing the chassis for our truck project. I am estimating a finished weight of less than 3500#. My plan was to use the Wilwood 13" 6 piston set-up on the front and the 12" 4 piston setup on the rear. I was also planning to run dual master cylinders, 3/4" bore for front and 7/8 or 1" bore for the rear. It is my estimation that this combination will provide excellent braking with normal pedal effort. I would rather not run power assist. Anybody have any comments? This is going to be mainly a street truck, it may or may not ever see a track. It will however have alot of power so it should also have alot of stopping power. Thanks for any input.
