My sympathies. The Brembo bolts are kind of infamous for doing that and I'm not really sure if there is any way to really prevent it when you're maintaining them (other than maybe replacing the bolts every time and using copious antiseize). They get really hot because they're massively heavy cars that are frequently driven hard.

I picked up a red top gel cell 1000 CCA battery for my Jetta about a year ago, I love the damned thing.

I've had one in my Forester since 2005, and it's still working perfectly despite having spent five years in 110F summers and -40F winters. So far, the battery has outlasted a center differential, one set of accessory belts, two sets of tires, three windshields, and a set of front brake pads, so I'd say the extra $40 that battery cost was probably worth it.

Picture to follow. I am in the midst of a nightmare.

My nephew brought over his 2006 Subaru WRX Sti so we could replace the front rotors, which are warped. Figured it'd be a one-hour job - it's two bolts per caliper, and nothing holds the rotor on.

Started at noon on the passenger side. The first bolt was sticky but came out. The lower bolt sheared off.

We have spent the last five hours trying to get this loving bolt out. After constant application of a propane torch, we managed to move it a sixteenth of an inch (about 2mm) before shearing off the rest of the bolt. I went through seven drill bits trying to drill it out to relieve it, as well as three pairs of Vise-Grips, which were the only thing that would hold on to the stub.

This is a Brembo caliper, which is apparently as rare as unicorn farts, and appears to be about $1000 at the dealer. I'm trying to track down machine shops, no mean feat on St. Patrick's Day Sunday. The car is now undriveable and in my garage, where it may remain for quite some time.

Can you weld something to the stub and twist it out with that? Or crush a vise-grip on the top + bottom end of the bolt and turn it? Or squeeze it in an actual vise?

Continuing what Black88GTA said, you could weld on a replacement head and take the vice grip or breaker bar to that, but also keep carefully heating that surrounding housing with the torch like you have been to give it a little more wiggle room.

The only concern I have with welding on a head is that seam will most likely break easier than the original head, but at least you'll get somewhere with it before it does.

EDIT: To remove any doubt, I am a lovely welder though, so you'll probably have a much better time with it than I have in the past.

Yeah, try heating the surrounding housing and then shooting the bolt (and ONLY the bolt) with freon spray. You might want to hold your breath while doing this, and/or do it outside with a bit of a breeze going.

As soon as you do that, IMMEDIATELY try turning the bolt. In fact, make sure you have your pliers clamped onto it before you shoot it with the cold spray.

Just drill it out. If you go from the back it might even catch and turn itself out once you remove some material. Those threads are going to be toast anyway so it doesn't matter if you have to go through the whole thing.

Going from the back won't help (it'll just screw what's left of the threads "in" and out the other side instead of backing them out) but a left handed drill bit sometimes will.

Honestly, I usually prefer to use a dremel to grind the end of the broken-off stub perfectly flat, then center punch it as accurately as I can and drill through with a small drill bit, making sure to have it absolutely perpendicular so the hole ends up perfectly straight down the center of the bolt. Then work my way up with progressively larger drills till I can see the peaks of the threads starting to show through. Carefully continue till the only remnant of the bolt is the threads themselves, then use a sharp strong pick/awl to pick the threads out of the hole and run a tap through it. Usually you only have to pick out the first 2-3 turns worth of threads, once they're out you have enough to get a quality tap started and it'll chew the rest of the bolt threads to pieces a little at a time.

Had to do that on the turbo mounting flange on the exhaust manifold for my M54A2 because I didn't feel like spending a couple hundred on a salvaged manifold after breaking off one of the (severely rusted) studs. Saved the original threads in almost perfect condition.

That rusted from the outside... I've seen this a couple times on subarus. Actually the worst one I ever saw was on my own subaru.

Hopefully you get those replacements, but if that falls through you can cross those calipers to other cars. It's a pretty popular OEM offering. Volvo S60R, Pontiac G8 GXP, Mitsubishi Evo, Acura TL, and 1st gen Cadillac CTS-V all used the same Brembo calipers IIRC, and for some reason CTS-V calipers are stupid cheap. You'll just have to settle for a different color or getting them painted later.

They're not identical. Mounting and piston size varies so it needs to be another sti caliper. From the same side too because the pistons are staggered.

Had I an arc-welder, that would have been my first choice. I have no welding equipment (I can rent a MIG/TIG locally for a reasonable rate).

Only the top was exposed, a good, meaty 1/2-inch. Three pairs of Vise-Grips later, it sheared off. I was using galv pipe to lock down the grips, too, as well as an extension to turn the bolt.

Tried the vise after it was clear working on it on the car was a fool's errand; mine is a Soviet-made beast that weighs about fifty pounds and is lagged to the corner of my workbench on a 6" post, but the jaws could not get purchase no matter how much I dogged it down.

We were reduced to cutting flat sides with a Dremel & getting a pair of Vise-Grips on good, then heating the gently caress out of the journal with a propane torch. After 90-seconds of applied jet, it would turn. At 1/2-turn, we had to stop & reset the VGs. Then repeat the process. We got about three rotations before we ran out of bolt. Incidentally, while I was heating it I was applying ice cubes (all I had!) to the top of the bolt/VG. No joy.

I drilled it out with my cheap drill press, way off-center (naturally). After seven drill bits I gave up. Went out tonight & bought a set of the heaviest bits Lowe's had and was able to nearly center the hole using my patented idiotic "drill bit makes a good router with 3-in-1 oil" method. Tomorrow, it goes to a machine shop, where they have big-boy tools, and they should be able to straighten out my mess & get a Heli-Coil into it. I just wonder if the constant heating over 2-hours didn't kill the journal. The four piston seals are fine.

This was a very steep learning curve. Several different steps will be taken on the driver's side, such as:

Step 1: Shear Off Bolt
Step 2: Take It To Machine Shop.

I know this is post-horse-bolt but if you need to drill something out this is what I do.

*Make an indent in the centre. Using a punch or a particularly solid screw or nail. Just enough for a small drill bit to find purchase.

*Carefully use the smallest drillbit I can to make a pilot hole.

*Drill out with a bigger bit etc.

I usually go with a bit matching the circumference of the broken bolt and start with that, drill enough to get a centered indent, and then step down to a smaller bit to make the pilot hole.
