Caliper Bolt Stripped
 

Need help.

I just had new BT-014s mounted. I'm guessing the guy at the shop when he re-installed my front calipers he used an air ratchet wrench or something and I've now managed to totally round out the lower caliper bolt in my attempts to get it off.

Please post suggestions as to how I might get the bolt free. It's a total write-off, so I'm thinking about using my dremel to cut a slot. Even if I do this, I'm gonna need some major muscle to get this sucker off.

Trying to avoid drilling it out and re-tapping...

Get an "easy out" kit. You drill a small hole in the center of the bolt and stick the easy out tool in that hole. It is made such that when you turn the tool with a wrench it diggs into the bolt more as you loosen it up. The kits are very inexpensive and you can get them at most any hardware store or auto parts place. The kit will even tell you what size hole to drill for each tool.

Just a suggestion, I've used Torx bits to remove allen bolts when they get stripped. Just find one that is slightly bigger than the allen bolts hole and tap it in with a hammer, this will make it dig into the bolt in the areas that the allen wrench usually applies force. Then put your rachet on and give it a try. If it works then Yippe! if not move on to the easy outs.

mystikkowboy - does that ruin the Torx bit?

Thanks for the replies. I haven't butchered this bolt any further...yet. I'm going to my buddy who is a mechanic and has access to easy outs and the rest. I've considered jamming a 9" allen into the bolt (1 size up) and trying. If that doesn't work I'll try a torx.

Does anybody know the details of this bolt? I've tried to order more but they are back ordered, coming from Japan. I'm thinking of going to the hardware store and haven't an example on hand. Thought I'd give the list a try.

Thanks again.

marmaladeboy----- I've never broken a torx doing this, but there's a first time for everything. You just gotta be careful to get it in there strait and not crooked or you'll definitely break something and it might be your fingers.

My mechanic buddie had it out in about 5 minutes, just hammered a ratchet allen in and gave it a good steady turn. I feel so much less of a man...
But I'm happy it's out. Thanks guys.
