Additional Notes
- The Steyr S23 15S23 4x4 carries a brake fluid capacity of 1 liter for the hydraulic brake system, which is consistent with a service fill volume rather than a full system overhaul quantity.
- Under normal use conditions, the hydraulic brake system on the 15S23 4x4 calls for a fluid change interval of 18 months, reflecting the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point regardless of mileage accumulated.
- The 18-month change interval applies specifically to normal use conditions, meaning the 1-liter service fill is tied directly to that standard operating context rather than any severe or first-change scenario.
