I have an old Peugeot Team Proffessional that I am looking to upgrade the brakes on. It has Weinmann (I think there called Carrera) brakes on it now and I would like to install some newer campy brakes. The problem is everything I seem to find is "recessed nut" and this bike is not. What is involved in running recessed, or do I need to just keep searching ebay?

I was going to say see a doctor, but than I read the problem, I'm glad it's bike related

The brake bolt needs to be long enough to go through the frame and be bolted on, that's why many frames have recessed holes for the nut, it sits nicely inside the brake hanger. Modern brake all seem to come this way, you may need to search at a local bike shop for something to fit before you buy anything on e-bay.

I have an understanding as to how it works, my new Cannondale has the recessed type, but I was curious if the bolt was long enough if I could simply put a nut on the other end and run it as such. Or if it would be advisable to contersink my frame to accept the recessed nut (though I would rather not modify my frame if I didn't have to) any help is greatly appreciated.

I installed modern Shimano Ultegra brakes on my 1984 Austro Daimler after reading about it here. I drilled the rear half of the fork to allow the recessed nut to seat and then drilled through the rear brake bridge hole. Looks good and the stopping power is much better than the stock Weinmanns. Longer bolts are available if you want the old style mounting nut without frame drillng.

Thank you for the info, I think I will just purchase some good Campy brakes and install a longer bolt if necessary rather than drilling out my frame. Thanks again- WJF
