Additional Notes
- The Mazda RX-2 (1971-1974) and RX-3 (1972-1978) share identical brake fluid service specifications, with both calling for a check interval of every 6,000 km and a fluid change interval of every 12 months under normal use conditions.
- The 12-month change interval on both models is time-based rather than distance-based, meaning the calendar drives the service schedule regardless of how many kilometers have accumulated.
- Brake fluid level on both the RX-2 and RX-3 is specified as maintained between the minimum and maximum marks, which is the standard reservoir band indicating acceptable operating volume without overfilling or running low.
- Both models reference a hydraulic brake system, which is the conventional closed-loop arrangement where fluid transmits pedal force to the calipers or wheel cylinders, making fluid condition and level directly relevant to braking performance.
- The 6,000 km check interval is notably frequent by general automotive standards, reflecting the sensitivity of brake fluid to moisture absorption over time and distance in hydraulic systems of that era.
