Additional Notes
- The Vauxhall Cavalier II (J82) hydraulic brake system holds a capacity of 0.5 liter across the 1.3, 1.6, 1.6 D, and 1.8E engine variants for the 1985-1987 model years.
- A 0.5 liter figure for a brake fluid reservoir represents a relatively modest total system volume, consistent with the sealed hydraulic circuits typical of passenger cars from the mid-1980s.
- The check interval for brake fluid across all four variants is set at 500 km under normal use conditions, which is a short distance interval reflecting how frequently fluid level verification was recommended during this period.
- The change interval is specified at 12 months for all 1985-1987 variants under normal use conditions. A time-based interval rather than a mileage-based one is standard practice for brake fluid, since the fluid absorbs moisture from the atmosphere over time regardless of distance driven.
- No variation in capacity or service intervals exists between the petrol-engined 1.3, 1.6, and 1.8E variants and the diesel-engined 1.6 D, as all four share identical 0.5 liter capacity, 500 km check, and 12-month change specifications.
