Additional Notes

  • Across all four configurations in the MINI Convertible R52 (USA) lineup, brake fluid capacity is expressed as "between min and max" rather than as a fixed volume. In brake fluid servicing, this phrasing refers to maintaining the reservoir level within the marked range on the reservoir body, rather than filling to a precise measured quantity.
  • The 24-month change interval applies uniformly to both the 85 kW MINI Cooper Convertible and the 125 kW MINI Cooper S Convertible, regardless of whether the vehicle is equipped with ABS or DSC. A time-based interval of this kind means the fluid is replaced on a calendar schedule rather than in response to mileage accumulation.
  • Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers the fluid's boiling point. The 24-month interval reflects the general industry understanding that brake fluid degradation is primarily time-dependent rather than use-dependent.
  • The R52 configurations are split between two stability control variants: ABS (Anti-lock Braking System) and DSC (Dynamic Stability Control). Both variants share identical fluid fill guidance and the same 24-month replacement interval across both power outputs.
  • All four rows carry a "normal" use condition designation, meaning the 24-month interval is tied to standard operating conditions rather than a severe-duty or first-fill scenario.
