Additional Notes
- All Opel Ascona C, J82 brake fluid specifications listed here apply to the hydraulic brake system under normal use conditions.
- The 1.3, 1.3S, 1.6D, 1.6S (1981-1986), and 1.8E variants all share a brake fluid capacity of 0.4 liter, indicating a consistent hydraulic system volume across those engine configurations for that period.
- The 1.6S produced in 1986-1987 carries a brake fluid capacity of 0.5 liter, which is higher than the 0.4 liter figure associated with the earlier 1.6S (1981-1986), pointing to a difference in hydraulic system volume between the two production periods of the same engine variant.
- A check interval of 500 km applies uniformly across all listed variants, reflecting a short-cycle inspection schedule typical of brake fluid monitoring practices where fluid level and condition are verified frequently relative to other service items.
- The change interval of 12 months is consistent across every listed variant regardless of engine type. Annual brake fluid replacement is standard practice because brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can compromise braking performance.
- The 1.8E variant carries a production window of 1982-1986, making it the only engine in the listed specifications that does not begin with the 1981 model year, while still sharing the same 0.4 liter capacity and service intervals as the other 1981-1986 entries.
