DIY-Bolt Extraction

[kidd_honda]

Well my caliper bolt broke in half inside, so i decided to do a DIY for people who might have the same problem in the future.Sorry for the pic quality. Crappy camera. The alternative: http://honda-tech.com/zerothread?id=567450 Heres what you need: -Goggles (Dont want to lose an eye) -Gloves (unless you want heavy crud under your nails) -Lubricant (Liquid Wrench or Wd-40) -No.1 Screw Extractor -T-Handle Tap Wrench -Drill with 1/8" bit -Hammer (not included in the pic). Craftmans 1/4 - 1/2in. Steel Tap Wrench = $4.99 Craftsman No.1 Screw Extractor = $2.99 Craftsman Specification: Screw Extractor----Drill Bit No.1---------------No.30 (1/8") No.2---------------No.12 (3/16") No.3---------------15/64" No.4---------------5/16" No.5---------------3/8" No.6---------------15/32" No.7---------------9/16" FYI: DO NOT GET THE SPIRAL EXTRACTORS. I HEARD THAT THEY BREAK EASILY. GET THE NON-SPIRAL ONES. 1. First, spray some lubricant in the area. Let it soak for 2 mins. or more. Then, drill in the center of the bolt using a 1/8" bit. Spray more lubricant after you drilled the hole. 2. Second, put the screw extractor into the hole and tap it in with a hammer.Get it deep enough to get a good grip on the broken bolt. Then attached the T-Wrench like so. 3. Finally, turn it counterclockwise and Viola!!! Bolt no longer OWNS me!!!! BOLT IS OUT!! THANKS FOR LOOKING KIDD_HONDA

Your pics illustrate the process well.

A different option that a mechanic friend told me about is to skip the screw extractor altogether. Buy LEFT hand drill bits--I found a set of 5 at the local auto parts store. Use a punch so that your drill won't wander when you start to drill (good advice whether you use the screw extractor method or not). If you're using the left hand drill bit be sure to run the drill in reverse. Normally, once the drill gets in a little ways the screw remnant will simply back itself right out. 9 out of 10 times I've used them it works just as described. The other 1 out of 10 I have to follow up with the screw extractor.

The only sound worse than a bolt breaking off is breaking off a screw extractor trying to get one out. They are a necessary tool, but I prefer to avoid having to use them if possible.

I don't understand why you have to do what you did. Were you working on a rear disk brake bolt on the caliper? I had recently a cross-thread bolt inside the pin on the caliper of a Honda Accord (6th generation) preventing the bolt from being tigtened or taking out. What I did was cutting bolt hax head off with a saw, and then pulled the pin out and discarded the pin with a stuck bolt inside. I bought a pin for $7 and a 8.8 metric bolt ($0.50) from Home Depot. I am not sure if I am speaking about the same thing as you did.
