Additional Notes
- The Sachs 4 Rock's brake fluid capacity is expressed as a range between the minimum and maximum reservoir markers rather than a fixed volume, which is standard for hydraulic brake systems where the fluid level is maintained within a defined band rather than filled to a precise measured quantity.
- Both the 4 Rock 50 and the 4 Rock F450 share an identical service interval of 24 months under normal use conditions, meaning the fluid replacement schedule is tied to elapsed time rather than distance or usage cycles.
- The 24-month change interval applies specifically to normal use conditions on both variants, which is the use condition under which the interval specification is given in the data.
- The hydraulic brake system note applies to both the 4 Rock 50 and the 4 Rock F450, indicating that the fluid specifications listed pertain to the hydraulic actuation circuit rather than any mechanically operated braking component.
