The reason it is hard is cuz you wont have power brakes anymore. They do offer different bore diameters so you can use the one that is best suited for your brakes.

Yikes, here we go again.
While you can make an aftermarket dual m/c system work with the stock brakes, I would advise against it. Unless you're willing to do some math and probably still have to try a couple different sized m/c bores.

The problem is that stock calipers need a lot of fluid volume. A one piston sliding caliper is less spendy to make, and a large piston is needed to spread the force out across the pad's backing plate. To get that volume the OE's use a large bore m/c. A large m/c bore makes for little leverage which means lots of pedal effort. Enter power boosters. Now we can have a large bore caliper with the required large bore m/c and still have low pedal effort.

If you want to go with the dual m/c system I would advise you to switch to aftermarket calipers as well.

Still not enough info. What piston sizes in the calipers?

The only booster I would consider using is a hydraboost. Keep in mind that all boosters have an assist curve designed for the original application. If your application isn't an exact match the brakes may or may not feel right.

So if you were going to use a cnc brake pedal/ master cylinder along withe the cnc 6 piston calipers on a 12.2" rotor would it work almost as well as the stock brake booster assembly? For specifics go to URLS:

That is too hard to say from here.
Can it be made to work as well or better? Depends on what the stock system is like and the weight of the tires and the vehicle. Brake system design is not the simple thing it looks to be. Way too many variables and each driver has their own preference.

My first *guess* would be that you want the 8.4 pedal ratio with a 1.0" M/C for those calipers. That will be a light pedal bordering on spongy feeling to some, but none of the other combos get in the right range for my rule of thumb. What does CNC recommend?
