Additional Notes
- The INFINITI FX S51 brake fluid specification applies across three configurations: the FX35 AWD, the FX35 rear-wheel drive, and the FX50, covering model years 2008-2013 for the FX35 variants and 2009-2013 for the FX50.
- All three configurations reference the hydraulic brake system, meaning the fluid level specification pertains to the brake master cylinder reservoir rather than a sealed or dry-fill service quantity.
- The fluid level specification of "between min and max" defines an acceptable operating range within the reservoir, rather than a precise volume measured in liters or quarts, which is characteristic of brake fluid service checks as opposed to full system overhaul fills.
- The FX50 shares the same "between min and max" reservoir level specification as both FX35 variants despite housing a larger displacement engine, indicating no differentiation in brake fluid reservoir capacity between the V6 and V8 configurations within the S51 generation.
