Brake fluid reservoir leak?
 

Anyone seen this before? The leak seems to be coming from the cap itself. No cracks around the reservoir that I can see. I see abit of corrosion on the booster surface. Not sure if that's something to worry about. Haven't touched this area since I did a brake fluid flush last year and made sure everything was clean and dry after that service.

Figure i'd ask here first before I go spend $50 (quoted in AUS) on a new cap from nissan...:rofl2:
I'll prob have better luck in the wreckers for much less.

Let me know what you guys think. Interested to see if anyone has experienced this. Car is about to reach ~68000km (~42250mi).

Yeah, it looks like the cap is leaking.
