Additional Notes
- Across all variants of the Audi 60/72/75/80/90 F103 series, brake fluid capacity is expressed as a reservoir level rather than a fixed volume, meaning the correct fill is any level that falls between the minimum and maximum marks on the reservoir.
- A min-to-max specification is standard for hydraulic brake system reservoirs, where the fluid level drops gradually as brake pads wear and the caliper pistons extend further, consuming more fluid volume from the reservoir.
- All six variants share the same min-to-max fill convention under normal use conditions, applied uniformly across the hydraulic brake system regardless of engine output or trim designation.
- The 60 variant appears in two distinct configurations for 1968-1972: a 40 kW version and a 48 kW Export version, both carrying the same brake fluid level specification despite differing in power output and market designation.
- The 72 variant covers model years 1965-1969, making it among the earliest entries in the F103 lineup represented in these specifications, while the 75 variant succeeds a similar production window with years spanning 1969-1972.
- The Super 90 spans the widest production window among the listed variants at 1966-1972, yet shares the identical brake fluid level specification as the lower-output 60, 72, 75, and 80 variants.
- The 80 variant, produced from 1966-1969, and the 72 variant, produced from 1965-1969, overlap in production years, yet both carry the same hydraulic brake system fill specification.
