Grab your VIN and go to your local GM/Chevrolet dealer parts dept. Ask them if they can run a (I think its the VIS report) to retrieve the RPO codes for your chassis. With your vehicle's RPO list, you can find put exactly what type of braking system and components were installed at the factory for your chassis. Or, you can check around the drivers/passenger area to see if the original RPO sticker was attached somewhere.
Once home, you can do an internet search for GM RPO codes and check each of the codes to see what was installed on your chassis at the factory,. Since you had only a chassis, you won't haver all the extra RPO codes that deal with paint colors, door trims, etc.
As an FYI, here's a list of RPO codes.
