My only experience with silicon brake fluid was on a tr3 ... A neightmare !
Each I release the brake or the clutch pedal it was making a jet in the fluid bottle encapsulating air bubbles and after 5 min there was so many air bubbles in the silicon that there was practically no brake anymore !
It take me hours to understand every morning brakes where ok and why after 5 min in a city circulation brake was practically ineffective.
Maybe it's due to the tr3 bottle or the tr3 brake and clutch master cylinder (both are identical in design) but I did not try again on other cars.
