Stripped thread on Fork, is it repairable?

I was being over excited fitting my front caliper on my suspension fork and accidentally over-tightened the caliper and consequently stripped the thread on the bottom bolt.

Now the caliper moves slightly under hard braking, meaning that when I release the one pad still touches the rotor.

 

Is this something that can be fixed, or am I in for buying new lowers?

 

Many thanks in advance for your answers and opinions

I have had the same problem before, the solution depends on how bad the thread is stripped, if its not too bad, running a tap through it may work, if its totally poked you can have a helicoil inserted either way it can be fixed.

And this one.

Don't ride with a loose calliper.  It will damage the mounts and no one that I know of has a mount facing tool that will work on through axles.  Makes it a very difficult repair.

 

First prize a re tap and longer bolt if possible.

genuine question - how does it being a through axle affect this?

 

This is an issue on one of the two mounting bolts for the caliper. (granted I don't fully know exactly what a mount facing tool is, but I think I can guess)

You need something to attach the facing tool to, and the axle is it.

 

OP - if you find yourself anywhere near Salt River, bring me the fork and I can sort out in about 10 minutes.

Helicoil. Had the same issue a while back on a used fork and got a Helicoil done, fork is still 100%.

 

Engineering shops should be able to help. I know Droo from stoke has a contact, perhaps give him a ring.
