I too am tired of waiting for the elusive MM update and this might be the answer I need to look into it and see how hard it will be to get the disc brakes back in there and fit the longer clutch unit in my CRT? I wasn't very happy with the motor braking anyway and wanted to put the brakes back in for more consitant braking and to get the brake bias back. :)
If you dont like to push it you can stack them both on the same side and pull them or use 1 rod for both brake arms? no prob I understand if it works why change it.
