Silicone brake fluid? You need a low-pressure brake light switch for DOT 5 silicone fluid compatibility...

Kube never even hinted at SILICONE brake fluid! Where the heck did that come from?

Silicone brake fluid goes through switches fast and going through 3 switches makes it a logical possibility. It is the first thing I thought of and I would have posted it but someone else already had.

Charlie, going through three new brake switches in the course of three days? Not likely even if silicone fluid were involved.
Nope, just bad switches right out of the boxes.
