Ford Ka Mk II, B420 (EU)

Brake fluid capacity & service interval

Ford Ka Mk II, B420 (EU) uses brake fluid with a capacity of 0,55 liter. Service intervals include checking every 1000 km and changing every 24 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Ford Ka Mk II, B420 (EU) brake fluid capacity of 0.55 liter applies to the hydraulic brake/clutch system, meaning the figure represents the total fluid volume shared across both the braking and clutch hydraulic circuits rather than the brake circuit alone.
  • Both the Ka 1.2 Duratec and Ka 1.3 TDCi Duratorq carry an identical 0.55 liter capacity, indicating no meaningful difference in hydraulic system volume between the petrol and diesel variants across the 2008-2016 model range.
  • A check interval of 1,000 km is specified under normal use conditions, which is a relatively short distance interval and reflects the safety-critical nature of brake fluid monitoring compared to other vehicle fluids.
  • The 24-month change interval applies regardless of mileage accumulated, meaning calendar time rather than distance driven governs when a fluid replacement is due under normal use conditions.
  • Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers the fluid's boiling point. The 24-month change interval for both configurations addresses this degradation mechanism rather than mechanical wear.
