Ursus 02/04 series
Brake fluid capacity & service interval
Ursus 02/04 series requires 0,5 liter of brake fluid. Service intervals include checks every 100 hours and changes every 800 hours. The data covers 4 configurations.

Additional Notes
- The Ursus 02/04 series hydraulic brake system holds 0.5 liter of brake fluid across all listed configurations, including the 1002, 1004, 1454, 1604, 902, and 904 models.
- A 0.5 liter capacity in a hydraulic brake system is a relatively modest fill volume, consistent with the closed-circuit nature of tractor brake hydraulics where fluid is not consumed but monitored for contamination and degradation over time.
- The check interval for the hydraulic brake system is set at every 100 hours of operation under normal use conditions, applying uniformly to all variants covered in the 1978-1985 production span.
- The change interval is specified at 800 hours under normal use conditions, meaning a full fluid replacement is due after eight times the number of hours required for a routine check.
- The 1454 and 902, 904 models share an identical specification profile with the earlier 1002, 1004 and 1604 variants despite entering production in 1983, indicating no revision to brake fluid capacity or service intervals was introduced with those later configurations.
- The 1604, introduced in 1979, carries the same 0.5 liter capacity and 800-hour change interval as the 1002 and 1004 models that entered production in 1978, reflecting a standardized brake fluid specification across the series from its earliest years.
