For the purposes of internet points, these brakes are good and work well with the speed and speedfit bindings. You might, as I did and a quick search, a bunch of people on another website with closed comments, did, in installing them. There is a plastic wedge piece that prevents you from installing the brake on an already mounted binding. All you have to do, is bake the whole rear binding off the mounting plate by adjusting the BSL adjustment backwards until it pops off the plate. With the rear binding unmounted from the mounting plate, you can easily remove the plastic 'spacer' preventing installation of the brake. Reinstall the rear binding onto the mounting plate, screw to desired BSL and then easily install the brake with the two screws included with each brake.
