Extracting a broken bolt (from a car)?
Yea, the only successful way I have ever removed a broken bolt, is to drill it out. I haven't had issue using the drill at workwith a bit here, when I had this happen to my old BMW I did some work on myself.
Edit: I should add that the drill at work is industrial though. So... lol

Posted by The_Mad_HatterGood lord, that's a lot of work when drilling it out is much more simple -_-
Brake bolts are held in with red Loc-tite and are hard as hell to break loose. They make an easy-out that will get the broken bolt out, but it's going to be rough considering the location of the bolt. You can also weld a nut (rose weld through the nut hole) onto the broken bolt and use a wrench to extract. The heat should help break the loc-tite loose as well. With either option I'd advise using some heat and PB Blaster beforehand and letting it set for a little while.
Posted by Superman77That's what figured as well, but wanted to make sure I was thinking about this correctly. Have you ever had to extract a bolt, car or otherwise?Posted by ChuckcemGet a drill bit that’s just smaller than the bolt. You can check it by inserting the bit into the exposed hole. Drill out the middle of the bolt and it will come out very easily
Since we don't have a car or metalworking forum here...Any car people here?
I was working on my car last week and planned to completely replace my front brake pads and rotors. I used a breaker bar to remove the two bolts that held on the main caliper. On my car the caliper also covers a separate caliper bracket that holds in the rotor. I tried to loosen the bolts on the caliper bracket with the breaker bar. After a few minutes the bolt head and a small part of the bolt body came off. The bolt had sheered in half, leaving the other half of the bolt still lodged in the bracket (imagine breaking a key off in a lock, leaving the key tumblers in the lock itself). This of course created a problem because I can't remove the rotor without being able to remove the caliper bracket.
It was then that I noticed that the bolts I removed from the main caliper had also broken and sheered off. Fortunately though the caliper bolts were screwed into caliper pins that are easily removed on their own and replaced (the caliper pin bolts screw into the caliper pins, not the caliper itself. By sandwiching the holes of main caliper between the bolt and the pin, the caliper stays in place.) I was able to easily take out the broken caliper bolts/pins and replace them with new ones.
Long story short, since I was able to remove the main caliper (albeit by breaking the caliper bolts/pins accidentally) I was able to replace the brake pads (which were not covered by the caliper bracket). So I put the caliper back on using the new caliper bolts/pins since removing the bracket in order to get to the rotor proved to be impossible. The old rotors look to be in good shape, but I'd prefer to replace them with new ones if I can.
It appears the bolts were put in place with an impact wrench (or possibly rust welded in place). My question is, aside from taking it into a mechanic has anyone every extracted a broken bolt on their own? I'm currently thinking about renting an extractor drill to remove the broken bolt, but not sure how much torque will be necessary. Also not sure if this would be more worth it than taking into a mechanic.click to expand
Posted by The_Mad_HatterGood to know. A buddy of mine suggest using hot water on the whole to heat it up as well.

With either option I'd advise using some heat and PB Blaster beforehand and letting it set for a little while.
Posted by nikkistarYeah I figured I'd have to rent a solid drill for this, instead of buying a handheld one that may not have enough power to do the job. Thanks for the advice. Do you work on cars for a living too?

Posted by ChuckcemNope. Never have. I just refuse to pay stealership prices on work I can do myself. BMWs are expensive AF to repair anywhere. The only thing I won't touch is replacing of any internal engine parts, like camshafts, rods, etc.., exhaust, and transmission. The rest just takes some patience.Posted by nikkistarYeah I figured I'd have to rent a solid drill for this, instead of buying a handheld one that may not have enough power to do the job.

They want ridiculous prices for things. Brakes are always a few grand quoted by them The rotors, pads, and sensors are about $ 200 per pair. Takes me about 1 to 1.5 hours to do each set. First time, took me like 4 hours. lol
But I also have the added benefit of having the tools here at work, to do it on weekends. I just grabbed some aftermarket HID headlights for my car that I am doing over the weekend. I have to take off my bumper, and disconnect all the parking sensors too. That's gonna be fun... not.

Posted by The_Mad_HatterDon't have to from the looks of it, but I always disconnect the battery when I do anything that had a direct electrical path. The headlights seem pretty standard, and the new ones are just plug in play. I think the height adjustment on the bracket is going to be the biggest problem I have putting them in.Posted by nikkistarPosted by ChuckcemNope. Never have.

Have you checked to see if you need kill the airbags?click to expand
Posted by The_Mad_HatterThat makes sense.Posted by ChuckcemYou probably won't need to. Brakes and the components around the brakes take the most abuse on a vehicle - think about the constant heat cycles. That's the reason many manufacturers use such strong thread locker (to counteract the expansion and contraction caused by heat) and why bolts break easier in that area. The bracket itself should be fine though as its not really mechanical.Posted by The_Mad_HatterI have half a mind to replace the caliper bracket too when I get that bolt removed.Posted by nikkistarBelieve me, I've been down this road many times, when dealing brakes..... it's never simple... especially as they get older.Posted by The_Mad_HatterGood lord, that's a lot of work when drilling it out is much more simple -_-
