Additional Notes
- The Proton X50 brake fluid capacity of 0.78 liter applies to the hydraulic brake system, which is the network of lines, calipers, and cylinders that transmits pedal force into braking action across all four wheels.
- Both the 110 kW and 130 kW variants of the 1.5T engine share an identical brake fluid capacity of 0.78 liter, meaning the difference in power output between the two configurations has no bearing on the brake fluid volume specification.
- The 0.78 liter figure represents a relatively modest total system volume, consistent with a compact SUV hydraulic circuit where the reservoir, master cylinder, and brake lines together hold a limited quantity of fluid.
- Both configurations carry a normal use condition designation, which in brake fluid servicing generally corresponds to standard road driving rather than high-heat or track-oriented use cycles that would otherwise accelerate fluid degradation.
