Ron not sure but the calipers are stock ZR-1.

Wait! I thought this car was built by professionals?

WTF......

You need a larger master cylinder than the 7/8".

DO NOT LISTEN to people telling you that you need power brakes. That is utter crapola. Trust me -- the right combo of brakes and master cylinder.... that thing will stop on a dime.

Amazing that so called professional builders don't know how to do math on critical items.

Manual, 7/8 bore master cylinder per the original post.

Curious to see where this goes. I know Larry Woo recently went to carbon brakes with a manual master but I don't know any details regarding that setup.

I have Carbon ceramic rotors on my 911 Turbo S ---- they require NO HEAT to work great.... They don't create dust.... they don't squeal.... Mind you, Porsche seems to be pretty good at engineering stuff.

Are those manual brakes?

First ... it is so hard for me to trouble shoot something with as many variables as a brake system ... when I didn't design the package.
I talked to my sharp friends at Brembo USA/Race Technologies & they can not offer any technical support for this package, because:
1. It was engineered as a total Corvette power brake CCM system for GM
2. You don't have the total Corvette power brake CCM system
3. Brembo does not offer an aftermarket CCM brake system for Corvettes ... power or manual
4. Brembo does not offer an aftermarket CCM brake system for any custom or Pro-Touring car/application ... power or manual

Second ... there are two different routes to correct your brake system:
A. Have the system engineered & see if everything you have is correct. If not, correct it. If the system is engineered correctly, then you know there is a "wrench problem" and you need to have a brake expert trouble shoot the install & bleeding process on the car.
B. Have a brake expert trouble shoot the install & bleeding process on the car. If this fixes it ... great. If not, you know the system is not properly engineered, so you need to hire a brake engineer to evaluate & potentially re-engineer your system.

Third, and I am only 50/50 on this. To a degree ... but definitely not 100% ... I "think" this is an engineering issue, caused by adapting a "part of, but not the whole system" from the Corvette. Especially converted it to manual, when it was designed to use the highly efficient C6 dual booster system. With CCM & ABS, these can be complex systems. But on the other hand, it could be as simple as you have air trapped in the system you can't find. Since I didn't design the system, I simply don't know.

Best wishes !

I did do some checking on that exact thing your talking about Ron , What I'm finding out is the Brembos on the Corvette are no different that the exact same model you can buy off the shelf from Brembo. Now I can be getting some bad info I'm not sure . I think the only guy that can maybe answer that is the guy I purchased them from (MARK S) and I'm about to send him an e-mail to get his thoughts .

The piston diameters etc are in the link I posted earlier in this thread. I thought the calculations I listed in that same post would be possible with those piston diameters.

Front:

09-13 C6 ZR1
11-13 C6 Z06 Carbon
Edition
Brembo 30/34/38mm 6 8.52 sq. in. 5497.8 sq. mm

Rear:

09-13 C6 ZR1
Brembo 30mm 34mm 4 3230 sq. mm

Rotor info is in the same link.

Don
