The principal difference between a centerpull caliper and a U-brake is that the arms of the latter are designed to be mounted directly onto braze-on frame or stay bosses, without the traditional slightly flexible mounting yoke. U-brake bosses are mounted above the rims, in contrast to below-the-rim cantilever or V-brake bosses, and the brake control arms cross each other between the cable connection points and the pivots. U-brakes were popular on late 1980s mountain bikes with under-the-chainstay brakes, and they are now seen primarily on BMX machines, many of which erroneously have only rear-wheel braking.
If you do not mind a bit of repainting and expense, one option is to ask a competent mechanic to braze on a set of U-brake bosses.
