Glue for Carbon Frames?

The little "lug" on the top tube that holds my rear brake cable in place has broken off my carbon frame.
Can I glue this on? If so what sort of glue can be used with carbon?
Any help appreciated as frame is useless without this lug.

what is the frame? As it may be best to contact the frame maker to check they have not done anything odd.
But i would say most epoxy glues will be fine.
But you "could" just run a full length outer for "now"."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Thanks for the response.
I have just glued it using Araldite Quick Bond (Clear). Let's hope it doesn't dissolve the rest of my frame.
It seems to have taken ok. I'll give it another hour or so before I feed the brake outer cable into it.
Thanks Again.0 -

I would be too embarrassed to as it was my stupidity that broke the lug in the first place. I tried to pull the rear brake lever and it wouln't budge (as the rearbrake was obviously siezed). I then pulled the rear brake harder and the outer cable broke the retaining lug on the frame.0

That sounds like the sort of thing a frame should really be able to handle - you were only applying forces in the normal way. After all, what's to say you might not pull the brake lever that hard in an emergency? You'd have a perfectly legitimate warranty claim IMO - though you've rather spoiled that now by gluing it back on.
What I'd be concerned about with your fix is that whilst it's not going to harm your frame and will bond OK, I'd not be sure how the strength might be affected - my gut feeling is that the Araldite you used is likely to be lower strength than what they originally used. As you've demonstrated you do need strength in this area (and the bond failing is potentially safety critical). Given all that, I'd still be tempted to enquire from where you purchased the frame / the manufacturer about a proper fix, even though you have probably lost any chance of a warranty claim.0
