I'm not well versed when it comes to French bikes, so if I'm asking a dumb question, chalk it up to a newbie to Mafacs and Peugeots. I picked up this Peugeot frame a while back to obtain the Mafac Racer brakes for a UO-8 I own. When I went to remove the Mafac brakes, I found the rear brake is mounted with a vertical bolt instead of horizontal. Are all Mafac Racer's mounted that way or is it just this particular Peugeot that used this style?
BTW, I've decided to not remove the Weinmann brakes currently on the UO-8.
