Additional Notes
- The Opel Ascona A hydraulic brake system holds between 0.37 and 0.4 liter of brake fluid across all listed engine variants, reflecting the total fluid volume the system accommodates under normal use conditions.
- The capacity range of 0.37 to 0.4 liter rather than a single fixed value accounts for minor variation in fill level between individual vehicles, which is common in hydraulic brake systems where reservoir geometry and component tolerances influence the precise amount retained.
- All four variants — the 1.2 S, 1.6, 1.6 S, and 1.9 S — share an identical brake fluid capacity specification, indicating no meaningful difference in hydraulic system volume across the displacement range covered by the Ascona A lineup from 1970-1975.
- The 1.2 S variant carries a narrower production window of 1972-1975 compared to the 1970-1975 span of the 1.6, 1.6 S, and 1.9 S, yet the brake fluid capacity remains unchanged at 0.37-0.4 liter regardless of model year within each variant's range.
- The specifications are tied to normal use conditions, meaning the 0.37-0.4 liter capacity figure applies to standard operating environments rather than any modified or severe-duty context.
