Putting a brake in your product line isn't all too hard. They've got this catalog over in Taiwan that has all the parts. If you you pay a few cents extra, they'll even print your name on it. Job done. The hard way is designing the brake from the ground up, like the people from Free For Ride did with the Clito brake. You'll need people for the design, the 3D drawings, the packaging and a team to test it all. But then, you can be proud on the finished product.
