Need help fixing carbon crack

Postby Gumgardner » Wed Jul 13, 2011 2:00 am

Hi. I need help from someone who works with carbon. I have an AX Lightness brake spring that cracked at the 'T' junction. The spring isn't cracked. It's closer to the part that connects to the brake. I don't know much about how it works but it seems to me like this could be patched with a strip of carbon. Does anyone have the ability to do this and would be willing to try?
It's a very small crack. It sort of looks like a tear in the carbon. It's still one piece. It hasn't cracked the whole way thru. It's right at the tip of my thumb in the picture.

Seems like for what they charge for 'em this should be covered by AX.
I buy everything that JMT lists on this site.

Hi!
If AX lightness won't cover it, then I could help you. It wouldn't be a problem to fix it, it would be possible to make even a new one..

Thank you for the offer. I just emailed AX again to see if they will fix it for me. If not, I would really appreciate it if you could patch it for me. I've been admiring your custom jobs for sometime.
Thanks

I attached a picture of the carbon spring relative to the 'stock' metal spring. You can see that the vertical component of the carbon spring is shorter than the metal one. As a rest, it doesn't fit inside of the brake as well. When I emailed AX they said they only make one size and they have to sand away part of the brake to get the carbon one to fit. It doesn't make sense to me why they just don't make the carbon spring longer.
