Additional Notes

  • The Iveco Daily 42 hydraulic brake system holds 1.11 liters of brake fluid across all five variants listed — the 42 S 14, 42 S 16, 42 S 16 3.0, 42 S 18, and 42 S 21 — with no variation in capacity between them.
  • A capacity of 1.11 liters is consistent with a service fill figure, representing the amount of fluid held within the hydraulic brake circuit rather than a full system overhaul volume.
  • All five variants share a 24-month change interval under normal use conditions, meaning the fluid replacement schedule is tied to elapsed time rather than distance traveled.
  • Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers its boiling point and reduces braking performance. A time-based interval of 24 months reflects this degradation mechanism regardless of mileage.
  • The specifications apply uniformly across the Daily 42 S range starting from 2024, covering variants with different power outputs — from the 42 S 14 at the lower end to the 42 S 21 at the higher end — without any differentiation in fluid capacity or change interval.
