Proton GEN-2 / Persona

Brake fluid capacity & service interval

Proton GEN-2 / Persona uses brake fluid with a capacity range between min and max. Service intervals include checking every 9000 miles or 12 months and changing every 27000 miles or 36 months. The data covers 3 configurations.

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

TypeSpecifications

  • Use: Normal
  • Between min and max.
  • Check 9000 miles/ 12 months
  • Change 27000 miles/ 36 months
GEN-2 / Persona 1.6 (2004- )
  • Use: Normal
  • Between min and max.
  • Check 9000 miles/ 12 months
  • Change 27000 miles/ 36 months
GEN-2 / Persona 1.6 ecologic (2004- )
  • Use: Normal
  • Between min and max.
  • Check 9000 miles/ 12 months
  • Change 27000 miles/ 36 months

Additional Notes

  • The Proton GEN-2 / Persona hydraulic brake system does not carry a fixed fluid volume figure. Instead, the specification calls for the fluid level to sit between the minimum and maximum marks on the reservoir, which is the standard fill reference for a sealed hydraulic brake circuit rather than a measured service quantity.
  • A check interval of 9,000 miles or 12 months, whichever comes first, applies under normal use conditions across the 1.3, 1.6, and 1.6 ecologic variants.
  • The change interval is set at 27,000 miles or 36 months under normal use conditions, meaning brake fluid is renewed roughly every three years or at every third check cycle based on mileage.
  • The 36-month change interval reflects the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point regardless of how many miles have been driven.
  • All three engine variants, the 1.3, the 1.6, and the 1.6 ecologic, share identical check and change intervals, indicating no differentiation in brake fluid service requirements across the lineup starting from 2004.
  • The dual-trigger format of the intervals, expressed as both a mileage figure and a time period, means whichever threshold is reached first determines when the service is due, a common approach for vehicles that may accumulate low annual mileage.
