How 'bout the SunTour RollerCam? (Most mountain bikes have cantilever brakes, with the bosses mounted below the rims, but mine has bosses above the rims, requiring the use of true centerpull brake calipers.) I have a RollerCam on the front of my mountain bike, w/ the cable routed through a vertical hole in the Nitto stem. The rear brake is a Shimano centerpull mounted under the bottom bracket. W/ salmon KoolStop pads and 4-finger motorcycle-style brake levers, I have no complaints about stopping power!

I have the original ca. 1960 Weinmann 999s (610F/750R) on both Capos, including the original levers on Capo #2 and period correct Weinmann levers on Capo #1. I built the Peugeot w/ a Mafac Racer in front, a Peugeot-branded Weinmann 999/610 in back, and KoolStop salmons, w/ good results.
The only brakes I dislike are the early Campag. sidepulls on the Bianchi. Shimano aero levers helped a bit, as did KoolStops, but I would still prefer a bit more stopping power. When I tried some nice-looking Shimano pads, the lack of braking power was downright scary.
