My 20000 km service was 74 euros but the brake fluid was not changed. I wonder why brake fluid is changed on 7800km?

I believe according to Mazda maintenance schedule, brake fluid should be changed every 40000km or 2 years, whichever comes first.

Brake fluid is hygroscopic, so it's more about the age rather than the milage.

Ach so, erstzulassung 9/2020. That explains it.
