I've been riding Mafac LS2s on a Peugeot PRO 10 team bike since the early 1980s and never had a problem with them. They are not wonderful stoppers in the "dual pivot" sense, just typical of the time. I don't think the blocks are as good a compound as they could be however, and remember seeing one of Phil Anderson's team Peugeot he rode in the TdF with Campagnolo brake blocks fitted to the Mafac holders (the holders have a cool arrow cut out of the holder to show direction of mounting). I always thought the lever was striking with the back filled in and completely smooth, and "MAFAC" actually pantographed in the front.
