Brake axle nut thread gone

Hi,

Put a brand new (budget) front brake onto my fixie, that I couldn't tighten properly, it was sitting loose in the fork. Kept trying and probably damaged it, so now I can turn it both directions, but it doesn't tighten or loosen at all even if:

• I take the wheels off and hold the nut with a wrench, whilst turning the brake itself around.
  
• Holding the axle and turning the nut.
  
• Wedged directly behind the nut putting pressure on and trying to unscrew it.
  
  

Any ideas how to take it off the fork? Thank guys.

Hacksaw.

Have you tried to twist it with your wrench while leveraging a big flathead under the bolt?

Hi,

Keeping the hacksaw as a last resort. Sadly the flathead didn't work. Thanks though

Not helping,
but,
every thread should have a theme tune.

Mole grips? They might work if it's the nut threads that are gone. If the bolt threads are gone then just hacksaw it off and buy a better caliper, here for example.

Ring spanner on the nut to undo and pull the calliper. You may get away with just a new nut and the bolt thread be ok.

here thanks you! Haven't got a mole grip sadly. Thanks for the tip on the brakes though

Thanks, will try!

I think the opposite end of the problematic bolt should have a head on it that accepts a Allen key. If you were to dismantle the calliper in situ you could get a Allen key into the bolt head then hopefully unscrew the nut.... If you're in London I'll happily give you a hand.

Mole Grip+Hacksaw did the trick. Bolt thread was gone in places, just enough to jam it. Thanks anyway! Will get one of them brakes from the listing👍

That’s very much appreciated, it is sorted now.
