I could have ripped my hair out over these brakes. They would not work no matter what I did. The best I got was to make them drag a lil, but then they got hot and the metal pads weldedthemselves to my differential uprights. It turns out that the cams were posistioned wrong from the factory. The picture in the owners manual is not too clear on the correct position of the brake cams. So to put it simply. I doubled up the brakes, Metal pad, disc, metal pad, disc, metal pad, on both sides, put in a E-9001 9kg. (equals 125 oz. in, part #83015 from
www.himotoracingusa.com $25.99) With the cams in the correct position, I got nothing to complain about. Stops very well, FINALLY!!! Thanks Eddie
