I'm pretty sure they should all be the same size.

So just out of curiosity I pulled the 12mm bolts out and threaded the 14mm right in... I pulled both 12mm bolts out and they are both different. you can see in the attached photo the 14mm bolt is the far right one. the 2 on the left are from the caliper... I think I am going to just go buy some 14mm bolts so they all match. is that a good Idea? from what I can tell from the boxes there is 2 for the left side and 2 for the right side.

If it's just the wrench size that's different, then it shouldn't matter too much. As long as it threads in and is of similar length, you should be fine.

Also, I have found out that a bolt from a hardware store might have a different head size than the factory bolt despite having identical bolt diameters.

I've realized through this project that there is a difference in bolt head size vs bolt size depending on if the bolt is JIS standard or ANSI/ISO. I have a lot of JIS bolts from Japanese sportbikes and the same size bolt takes a different wrench on some of them vs. the stock Cobalt stuff.

Re manufactured when they rebuild calipers the use the bolts they have in their bin. The head is the only difference the bolt diameter has to be the same. I have seen one with torx head and one hex head bolt.

Just a FYI if you go ask for 14 mm bolts they will never fit the hole. Bolts are measured by the thread size not the head size. I think those are 8mm bolts.

Personally, and I need to heed my advice here too, but I would replace them so everything is the same size. You don't realize how far of a trip to the toolbox it actually is if you forget and have to go get another sized wrench. Even if the toolbox is within arm's length, it still feels a mile away.

Am I supposed to loctite these 4 bolts?

In my opinion, if you can't afford for it to come loose, Loctite it. I would red loctite the stud to the hub, or at least blue Loctite. If the nut isn't a lock nut, which I believe it is, then I would Loctite it also.

does anyone have the link to the wiring harness diagrams?

for the brakes do I need 4 sets of front brake pads?

Along with a few other builders, I'm also running the Duralast Gold DG956 pads.

The kits use four sets of front calipers from a base cobalt. They are all identical with the exception of driver/passenger sides. I think for the SS/TC's only, the rear caliper brackets are machined because there is a tab that sticks out which will interfere with the knuckle.
