#32491, "RE: Brake light wont go out when cold" In response to In response to 1
What you are seeing is contraction of the brake fluid because of low temps. Just like how metal expands/contracts as temperature fluctuates, fluid does the same thing.
Our brake fluid sensors are extremely sensitive to this slight decrease in fluid level.
Solution: Add brake fluid. The light will no longer come on in cold temps. (speaking from experience)
