Fellow List members, I am building up a beautiful golden Vetta frame and tried to assemble the BB-Cups. For some unknown reason the left BB-Cup will not go in as appropriate. I have reamed the threads with the proper Campy die tool (several times)and tried various different 24x36 threaded cups, none but one older used Rino right cup will go in well. All others will get stuck after some turns to an extent that i even broke the pins on my BB-wrench. I am totally clueless here since I do not want to ruin the pinholes or the wrench using to much brute force. I have, over the years, mounted a lot of cups, but it was never as hard as this time. I even tried some grease or WD 40 as lubricant without success. I have to say that it is fully chromed frame and i faced similiar problems but not as stubborn as this one on other chrome frames. Does anybody her have further ideas or hints? I suppose those left BB cups with the pin holes are not designed to be mounted forceful. The right cup was hard o mount too, but since it has the flats it was easy to use some more force, again with the proper Campy tool designed for this. Should I try to mount a right cup with more force to "loosen" or "widen" the threads? I suppose there is no special tool with more than two pins for this task?
Regards and thanks for all assistance

I can second that. I have a Raleigh Gran Sport with these brake which i gave to friend who acompanied me at last years L'Eroica. We did the 75 km ride and he is not an experienced rider on this kind of bike or on longe distances. The bike is all original including the original NOS red Weinmann brake pads. He did very well in braking those longer gravel and asphalt descents. The bikes constitution after the ride was far better than the riders constitution, he needed some time to recover afterwards since his back was not used to riding on a race bike. What more could you expect from a brake than performing well in this conditions?

Weinmann Vanquers are strong calipers. Setup tips include the usual pad contact concerns (no excessive toe), plus the consequences and remedy of overtightened pivot bolts. It's sometimes necessary to dismantle them and sand down either the bushing flanges or arm mating surfaces to match the effectively-shortened pivot sleeves. The pivot sleeves can flare out and/or dig into the main arch if the pivot bolts are heavily tightened, and the only remedy is disassembly as described.
A home-made booster arch added to the front will further limit flexing if the lever travel is excessive (you'll need longer bolts). I've used these over the last 12 years for nearly all of my XC, CX and crit use, and mine are the 750's using the boost plate in front and aftermarket pads. The XC use really tested them with steep descents in wet conditions. They are not the easiest caliper to reassemble, but not that hard, either. Don't forget to polish them up and maybe lube pivots with Gripshift grease while you have them apart.
The 610's have more leverage but will exacerbate excess lever travel if too much toe-in is used. The stock pads are quite mediocre imo.
