Silicone ( dot 5 ) is Not used in New Cars because most all have ABS.
The very fast pumping action of the Anti Lock actuator causes silicone to foam.
Also, the Cost for car manufacturers to put dot 5 in all the cars they build,
would cost about 4 times more than dot 3.
Plus, they make money selling you new brake parts every few years.


I've used silicone ( dot 5 ) in many of my old cars for many years, and
I would never change back.
I recommend using a mechanical brake light switch with dot 5.
If you spill silicone fluid on your paint, you just wipe it off.
Spill some dot 3 or 4 on your paint and you'll have to dig out your wallet.
