I live in Colorado and most of the year I have no problem w/my brakes, however, the few times a year when it is very cold out (below zero) my brake light comes on and I find that my brake fluid reservoir has fallen into the low range (but never below). This problem has been going on for years.

I should also note that even after it warms up my brake fluid remains low and the light stays on, so I don't think it is simply the contraction of the fluid. Also, I looked around the brake reservoir / wheels and have not seen any leaks.

Does anyone know what may be causing this problem? Any help would be appreciated.

Evaporation?

 

Inspect each wheel's caliper for leaks.

 

I'll take another look.. I need to replace a CV axle so maybe I'll do that myself and buy a jack and jack stands so I can get better look at the callipers..
