Well I got sick of having to keep the car under 4k, so i spend the $3 and bought another bike brake cable and fixed it. In order to attach the cable to the plastic wheel inside the IMRC, I modified it with a dremel the first time so it would hook in. I could still use a fresh cable though, so email me if you have one. Oh......the secondaries don't seem to be gunked up, the force needed to open them seems like its just spring tension. Hopefully this cable lasts longer, IMHO the whole design of the IMRC seems stupid as f***
