Converting Brake mounting bolt to recessed bolt?
Hi there.
I have a pair of old Shimano N-600 single pivot brakes I want to put on my repainted MIELE Uno. These brakes are the nutted type and I want to use recessed nuts on them. Is there any reason I can't just use a die to cut more thread on the existing bolt and then cut off the bolyt shorter for the recessed bolts? Does anyone know what die threading I'd need for these threads? Thanks again from Peter |

Hi there. I don't want to spend $60 - $80 for new calipers (quoted price) when I have a perfectly functional pair right here that only need a shorter brake mounting bolt to be perfect for *ME* to use on this bicycle. Mounting fenders is not all that much harder with brake calipers using a recessed mounting nut - I know because I have done that lots of times. I was thinking about ctting more threads on the existing bolts because that would save me a trip to the LBS tomorrow ro scrounge the parts bins for new recessed mounting bolts from another set of brakes. I'd rather spend that time tomorrow riding my other MIELE. Cheers from Peter |

Cutting two lengths of tube is much easier than cutting and threading an already hardened chromoly mounting bolt btw. |

I'd be interested in the source for this claim that Shimano N600 brake bolts are a) "chromoly"; and b) hardened of course, if it's of the nature of "my 'experience' says so, and I'm dead clever, I am", that will get the weight it deserves. |

I doubt they are CrMo and they are certainly not hardened (having threaded them). -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

I was giving my experience of hardened brake pivot bolt. I was not being specific to model. I suspected it may apply to 600 calipers at least in some markets. Using a dot punch on the end of the bolt will quickly determine if the bolt is hardened or not. Reliance on published data is no guarantee that the bolt is one or the other. |

Since the rear brake is oriented to present less danger of a failure, do it that way and use the factory threaded 'rear' bolt in front. Or of course alternately get a Shimano short bolt for the rear. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
