Caliper Bolt

Any suggestions as to how I would go about getting this thing off or any place you recommend where I can get the job done?

I took it to a shop when I first got the bike and they told me they were unable to get it off, they said I'd have to take it to a specialist.

I've got a 2009 ZX6R and this is the front brake caliper bolt.

Thanks for any suggestions!

i don't know if a hand held screwdriver will give you enough torque to remove that bolt, but a hammer impact with a screwdriver bit will - while preventing any slippage. at princess auto ~$20 with screwdriver bits. i'm still using mine after more than a couple decades! edit: and get a replacement bolt... use penetrating oil prior

would love you to name the shop that said " specialist req'd" lmao

$24 and has a larger bit selection http://www.princessauto.com/en/detail/9-pc-manual-impact-driver-set/A-p8311615e use a fine hacksaw blade or fine file to make the slit right size

and how to use impact - make sure impact is set to LOOSENING POSITION, not tightening, hold impact true and VERY tightly. and don't wack it girly like with the hammer the way this guy does - give it a good solid smart wack with the hammer!

if person who initially tried to remove bolt, and wrecked bolt head, used an impact in the first place you wouldn't be going through this - allen head bits can also be used with impact. One of the first tools that should be in every toolbox.

ok this should be easy
what you need is a star head (torx) socket.
you get one that is about the size (a bit bigger) of the bolt BUT you need to use a hammer to tap it in.
It will make new grooves and fit tight.

you should be able to remove with a socket wrench.

You can get the part alone from CT or Princess auto.

Buy a new proper bolt.

interesting. but i don't know if a torx bit hammered in will provide enough grip, given that it stripped with an allen key (unless allen key was wrong size.) heck, even vise grips with a hammer may do it. the beauty of an impact is it hammers the bit in while turning simultaneously

I've done it both ways. I usually try the torx first as it requires no extra cut. If that fails move to the first suggestion, and yes, use an impact driver (can also be used with the torx bit). If that fails I then move to drilling.
 
FWIW Ive used the "torx hammered in" method many times. I work in a machine shop and deal with socket head cap screws all day long. It works well. The KEY to success is bang it in good, be slow with the wrenching, use a pipe for extra leverage, and be square and perpendicular to the bolt as much as possible.

If all else fails, I have carefully drilled off the head of the bolts in the past, leaving just the shank of the bolt left which usually spins out freely after you remove the head.

I'm betting that's a rotor bolt but yeah I wasn't joking
 
That is an easy fix, if you have a clue....

No one has mentioned yet: HEAT, lots and lots of heat. Heat that bolt to red hot and you could take it out with a pair of tweezers. (That caliper heats up and cools down every time you use it. We call this heat cycles. Anytime you have heat cycles and a seized bolt; heat is the answer).
Heat and an impact driver: I'd have that bolt out in less than 5 minutes. (If you can't get something to go into the bodged socket in the bolt; TIG weld something onto the head, then immediately remove the bolt).

Which shop said "I'd have to take it to a specialist"? I always thought the persons found working at motorcycle repair shops were "specialists".
 
For the OP: If you want I will remove that bolt for you...

but I will have to charge you "specialist's" rates....

If I were OP I'd take that offer. You can learn a lot from this man

Be sure to get your hands on a complete caliper reseal kit if you heat it "red hot".All the seals will melt with that much heat.

Ha yeah red hot is a bit much. A propane torch for a few seconds should be enough

Lol, not only the rubber but also residue left from boiling brake fluid. The bolt is done for sure, take it to your local welder tig preferably 100 percent works or cut a slot then use impact flat not always works.
