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 !
