I agree. GM engineers thought it best to use larger hardware.

Well snag #2 this morning. I put it all back together last night, mind you i never removed the caliper/hose or opened the system.
So now im at a shop trying to get brake pressure back. The wheel i was working on has no pressure what so ever. Hopefully opening the abs module and a power bleeds get me out of this stupid situation.
Mind you i am an ase certified tech working at a parts store for a living i have no idea what the hell happened.

If you had it open long enough and let air in, you might need to use a Tech II to purge the ABS module...
Excited about this progress and I vote the 14mm bolts fwiw.

When you pushed the pads open did u remove the cap from the top
**** you auto correct!

Never messed with the master cap, I have pushed the piston back in twice before when I painted my calipers and i also had to remove a stone from the inner pad once before too. Again I never opened the system also. Ive worked on at over a hundred cars doing brakes, new ones old ones, never had an issue before this. Coincidence, probably not just cant figure it out in my mind.

Got an email that my brackets shipped, getting close to having everything!
I went out and pulled a wheel off to check some stuff out and to remove a caliper bracket bolt to get the length measurement for when I get the 14mm replacements. As I was putting the bolt back in I jiggled it around in the spindle hole and there is a little bit of play, I guess if the hole was exactly 12mm the bolt would almost be a press fit even before you caught the threads in the caliper bracket.
At first I was looking at 14mm drill bits but now I'm thinking a 9/16 would be better, not to mention much easier to find. 9/16 converts to 14.2875mm which would probably be the perfect extra amount.
So my question is this: Would 9/16 be a better choice over 14mm for the drill bit?
I normally don't work with these tight of tolerances so I'm out of my element a bit here. Other than that, the bolt is high strength, 40mm long, the flanged head is 25mm wide and the bolt is all thread.

My rear rotors and calipers were supposed to be here yesterday... Didn't happen. Then today...still no parts.
I have everything I need for the front and rear calipers arrived yesterday, no car to work on still at the dealer, will be till Wednesday.
Winner!!

Rotors arrived today, these are significantly larger than the originals. I did a mockup and took a few pics, the caliper is just sitting there since I don't have the new brackets yet.
I lightened up the photo's to make the disc's easier to see.

Also, if you want to swap over to the correct splash shields, they come off easily without having to remove the hub. The larger discs won't interfere with the original splash shields but since it's so easy to replace them I'm thinking about it. Edit: After looking up splash shields for a few different models, none of them really look right so hell with it!

do you have any pictures of the redrilling of the rotor? im tempted to do this, but from the picture, it looks like i'll need at least 17" rims to fit them. but that was going to be my next upgrade anyways.

Looking at the apparent size difference I suggest test fitting rims some 17" may not clear.
Unless, of course, you know your rim choice clear.

On gmpartsdirect site the splash shields on our cars dont match what we have on the car. But the encore shields look like ours on the site. I know there was someone who chimed in saying they have an encore, we need to see if he can take the wheel and brakes off and do a comparison.Rotors arrived today, these are significantly larger than the originals.

Heh, I'll take a wheel off for you but not the breaks. What if I just tried to get a shot from the backside? All u wanna see is the shield on the rotor right?
If I had nothing to do if do it, but I'm driving for uber today (and pretty much everyday) to for extra money.
**** you auto correct!

You can see it goes all the way around the rotor.
