Additional Notes

  • All six configurations of the Isuzu D-Max RT56 covered in these specifications share an identical hydraulic brake system fluid capacity of 1.2 liters, regardless of drivetrain layout or engine output rating.
  • The 1.2-liter figure represents the total fluid volume of the hydraulic brake circuit, encompassing the master cylinder reservoir, brake lines, and caliper or wheel cylinder volumes across the full system.
  • AWD variants spanning the 87 kW, 101 kW, and 120 kW output levels all carry the same 1.2-liter capacity, indicating that the addition of front axle hydraulic braking hardware in the AWD layout does not alter the total system volume relative to the RWD equivalents.
  • RWD variants across the same three power outputs — 87 kW, 101 kW, and 120 kW — also share the 1.2-liter capacity, confirming uniformity within the RT56 generation across the rear-wheel-drive lineup.
  • The specified change interval for all six configurations is 48 months under normal use conditions. A 48-month brake fluid interval is a time-based schedule, reflecting the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers its boiling point regardless of mileage accumulated.
  • The normal use condition applied uniformly across all rows means the 48-month interval is not adjusted for severe operating environments such as frequent towing, mountainous terrain, or repeated high-load braking cycles, which would typically accelerate moisture absorption and fluid degradation.
