Flushing-renewing the brake and clutch fluid every 2 years is recommended.
Has anybody used one of these on any of their vehicles?
LINK: Brake Fluid Tester - DOT 4
If so, recommended? Guessing it will help verify that the fluid is becoming (or is) compromised, encouraging regular fluid changes with data.
The LED lights will indicate the percentage of water in the brake fluid:
Green: None
Green/Yellow: Less than 1%
Green /Yellow/Yellow: Approx. 2%
Green/Yellow/Yellow/Red: Approx. 3% (Time to change brake fluid.)
Green/Yellow/Yellow/Red/Red: Approx. 4% (Change brake fluid immediately!)
