I went to some driving event a couple of years back and they had Brembo engineers on hand with a kiosk of their products. The subject of brake fluid maintainence and brands recommended came up and they said that if you weren't tracking the car, nor doing any kind canyon runs, they wouldn't bother with changing the fluid on a street car.
Take it for what it's worth.
now that is just stupid.
if you are tracking a car, you will know when to change fluid.
example. i spent last weekend tracking my car. 17 gti sport. i changed the front pads to porterfield r4 track pads.
did not change fluid. everything was fine. lots of track snobs will spout off motul and what ever fluid, but if the fluid is fresh it works fine.
this is in a car with ~10k miles on it. now at 15k miles i will replace and upgrade the fluid.
btw, canyon carvers are the posers of the i think i know how to go fast.
you cant get tires / brakes up to temp on streets or in canyons.
if you think you can you have not been on track! and you are driving like an asshole on the street.
