A few years ago I bought the aftermarket cpp brake booster and master cylinder. I got it and bolted it in for mock up but never used it. Some how, I have no idea how the booster assembly cracked and fell apart, seems brittle.

Does anyone know what kind of booster they are using? I think it's an 8 inch. The master cylinder is off a corvette I believe.

 

Looks like an aftermarket booster loosely designed based on the S10 booster. Most GM boosters I use have a mounting bracket, the S10 unit bolts directly to the firewall.
