I agree that some replica brakes are extremely poor, even some of our replica Lightning alloy plates have been far from satisfactory from what I've seen. I had a replica full width front hub where the new linings came away from the shoe with a light pry with a blade screwdriver because of a terrible ridge left in the center-line of the brake shoes themselves as the manufacturer could not be bothered dressing it off. I have to say that some of the replica brakes are far better than others, and it is worth noting that when considering buying one, that you buy one that ideally suits the size and weight of the bike. Not only that but some of the large top quality brakes are very expensive, between 2000 to 2500 pounds. I have had great success with an original but very much lightened Suzuki 750 GT brake, Three of the magnesium back plate 230 mm Ceriani's and I also have one of the Molnar replica Magnesium 250 mm Fontana's, this last one is probably the pick of the bunch and I haven't decided what will happen to it yet, but is sure is an awesome looking brake.......... Just fabulous.
