Brake bolt too short :-(

Posted on
  • Does anyone know of a brake i can run on the front that has a long bolt to attach it too the forks or where i can get a longer bolt from. The one i just tried to fit the bolt was too short. Ive kind of bodged it on for moment. But its not ideal by any means.

  • iv got the same problem on my bike, but when i bought it it already hada brake on it,you could try using a bake brake on the front, or using a nut in the middle of the forks, but that may be really hard to do, or you will have to drill a hole in the back of the forks, thats what they told me at brixton cycles, they also said they would drill it for me if i took the forks off myself, maybe they will say the same to you?

  • Sounds like you've tried to fit a rear brake on your front fork - the calipers usually have different length bolts for front and rear.

  • ok so you think this brake ive been given is a rear one? It makes sense that it could be a rear brake as you wouldnt need such a long bolt to attach it.

    So if i try and buy a front one asap then fingers crossed it sould fit fine. I'll measure it up before buying it. Cheers.

    While im on it anyone have an idea of how to remove rivets holding on a chain guard to the chain ring on an old raleigh. Maybe drill them out?

  • the one thats on the olmo? thats a front
    i'll see if i can find a longer nut tomorrow.

  • Rear brakes have a short bolt, front one s a long bolt.... however, on old frames even the long bolt of a modern front brake, such as a Tiagra or a 105, will still not go right through. The only option in my experience is to just attach the allen key 'hood' inside the fork rather than letting it go right through.... as long as it's tight it will be fine. I have 2 frames with this problem!

  • how short is the bolt? and what type of brake do you have?

    there was a moment of panic (ok slight exaggeration) when i tried to fit a shimano 105 front brake to the forks on an old frame. The bolt just made it to the back of the fork with no protrusion to screw in the nut. panic was quickly over when i realised that the nut (which is about 1 cm long and essentially engulfs the back of the bolt) is supposed to fit through the back hole with a wider lip securing it in place on the outside when its screwed in enough. All i did was drill the hole in the back of the fork to make it a bit wider. In my case i used an 8mm drill and it worked a treat.
