Only way to really know for sure would be to have the caliper (or possibly the whole car for that matter) inspected by a facility such as www.polytechnic-inc.com. They do failure analysis for machinery and hydraulic components, among other engineering services. From what I understand, they usually deal with law firms or insurance companies, as the work is very cost prohibitive; not even sure if they would deal with a private individual....I guess for the right price anything is possibile. But bottom line, if you wanted to know exactly what happened, they would likely be the best equipped lab to make that determination in the Chicago area.

are you saying the two halves of the caliper literally came apart? as in the one half blew off the slider posts?
that happened to me in my garage while putting my 12 bolt back in this year, but there was NO fluid in the lines.
also when I changed my WRX's front pads recently I couldn't pull them apart to re grease the posts until i had pulled the lines off so they were empty.
I'm no general mechanic but from those two experiences if that caliper blew apart then sounds like maybe you lost your brake fluid somewhere prior to trying to step on the brakes. anything you can think of that could have cause that to happen?

What does the inside of the rim that the caliper blew apart look like? Does it have marks/gouges from the caliper on it? Possible one of the caliper guide bracket bolts or caliper mount bolts either broke or backed out, taking the caliper out on the rim.

I'd vote for the bolts breaking being the issue. I could be wrong here, but doesn't GM say to replace those bolts when you remove them? I know I read that somewhere, but wasn't sure if it was for the rears or which bolts they were for that matter. I know one thing, if and when I ever get my car back, I'll be checking that out!

I would have to go with the caliper coming loose and hitting the rim theory, Even a ground caliper, if it were to fail due to the thinner material, it would crack maybe leak but not explode.

i have a feeling when you burned out the stress of holding the front tire in place either blew it there, or broke the bolts and the hanging calipur whacked the rim and exploded, the second one is probably what happened.

If he did lose the brake fluid there would be a trail of it somewhere throughout the run.
If you go with the burnout theory. Just my 2 cents. I hope that the problem can be figured out exactly, to prevent any other incedents.

actually, you can compress oil one-half percent of its volume. so technically, fluids can be compressed, but the result is minimal.
...sorry to hear about the car, i hate having mysterious **** like that happen, especially when it involves the compromise of life.
good luck with the recovery process.

I could run it through solidworks and cosmo and actually do an analysis of it. Showing the breaking point.. LOL

I don't think the linelock temps would change since the wheel nor the brakes are moving when doing a burnout. I would think it's from something else.

I'd like to contribute to the broken bolts theory that happend on my s-10 pass side caliper bolts backed out the caliper fell on the rotor and before i could slow down it rode on the rotor jammed it and actually broke the rotor machined surface away from the rest of the hub hear my warning GREASE YOUR SLIDERS at every brake job not only will it increase life and performance but it will keep them from getting stressed and breaking or backing out. sorry to hear about the car matt i was there the night you beat the blown malibu fun times especially afterwards when you DROVE your car home lol.
