Mafac made some adjustable reach mounting plates. The mounting plates (on the back) had vertically oval holes for the fitting of the center bolts. This allowed you to raise or lower the plate together w/ the caliper. The plates came on some of the Competition models and are interchangeable w/ Racers. You could try enlarging (ovally) the existing holes upward to get more drop.

I haven't tried this, Jon, but for the rear you might just be able to kludge this up with parts from a Pletscher rack mounting system. want me to send a set of leftovers?

Listers,
One of the biggest issues with our Peugeot UO-18s was that Mafac Racers no longer reached the braking surfaces of the 700C alloy (OT Mavic Open Pro) rims that replaced the mixte's original steel 27" Rigida "death-in-the-wet" rims. It took me a long time to find two sets of used Weinmann 750 centerpulls, and I still have the original Racers in the garage. And since (in all likelihood) I will be going through this process again with another "perfect-fit" UO-18 Mixte, I'd just as soon use up the inventory I have this next time around. But I still need another 5-8 MM of brake reach out of those Racers.
Have any of you ever heard of, thought about, designed, made, seen, purchased, or used a drop bolt (similar in concept to the ones used for Campi and Suntour Superbe brakes) for Mafac centerpulls?
