In the 4WD Toyota world OEM rotors and pads in particular are held in high regard. Enough so that sources for them outside of Toyota's mark-up have been found. I would suggest researching the Nissan forums to see if a similar sourcing exists.
Normal brake fluid is supposed to emulsify any moisture that gets into the system. Regular flushing then removes that moisture. It is a good overall system if the owner does their part. Road racers flush regularly because any moisture lowers the boiling point of the fluid. They also do not buy the large containers of fluid unless bleeding a new, dry system. They buy small bottles and leave them sealed until needed. All of this is to keep the boiling point of the fluid as high as possible.
Along comes silicone brake fluid and some owners think "now I don't have to flush as often because it doesn't absorb moisture!" Nothing could be further from the truth. With silicone brake fluid the system should be flushed much more often.
Why? Water is denser than silicone brake fluid. Give it enough time and it will condense into all of the local low spots in the system, and then start to rust or corrode whatever parts it is contact with. How do I know this? My Early Bronco that came out of the Puget Sound area with silicone brake fluid in it taught me all about this. I've no clue how it rusted a 'bath-tub' ring in the low spots of the iron m/c's reservoir under the silicone fluid, but it did.
