Are there any other rear master cylinders that fit the nc30.
Mine stopped working and require a replacement ASAP, or can you get a service kit for them.

Yes, you can get a service kit for them.......

I've got a CBR400 one on my NC35, the only difference is that the mounts on the CBR one aren't threaded, so you'd need to stick nuts on the end of the mounting bolts. If you can find one on eBay that's confirmed as being in good working order, it'll probably be cheaper than buying a service kit....
