The parts manual is exactly the same as the "real" one (see below).
Bikepics have removed the full size page, thanks a bundle.
The rear brake hose runs along the top of the chainguard and is held in place by a couple of nasty steel clips that are part of it and rust in seconds (exactly the same as the NC30 and 35) and then through loop 43350-MR8-780.
Jamie sells a nice rear brake hose stay or if your lucky like me your '28 came with a carbon hugger c/w brake hose guide.
My NC35 and MC28 rear brake hose setups, the NC35 is how the MC28 should be done, click for bigger (but still blue tinged??) pics
