Do you really need to change the fluid after a year?
What happens if you don't?
Would like to know since I'm considering changing to SRF but it is expensive
Normal recommendation for changing brake fluid in a car that sees the track is 6 months. SRF can be used for a year as it has an exceptionally high wet boiling point. (higher than the dry boiling point for many fluids!).

If this is a street car that is not tracked then SRF once should last forever. Ok. Maybe a decade. But you get the idea.
