cold weather and brake fluid level
just noticed today when i got up to do some shopping (after- thanksgiving sale
) that my brake light was lit. got out and check my brake fluid levels and it was a little more than half empty. i just filled it back up to full and problem was "fixed." this is the second time this happened. it was about 38 today and the last time it happen was on a cold morning too. my question is how can cold weather affect my brake fluid level? i never notice it on warm days. plus i don't see any visible signs of a leak. any ideas? thanks

It's probably leaking from one of the seals.
I used to have an old Celica when I lived in Colorado and it did the same thing when it got below freezing. It was pretty obvious on my car that it was leaking from the Master Cylinder as the bottom of the brake booster was wet with brake fluid, though.
If you have a GXE with drums in the rear, it may possibly be leaking from a cylinder there. That would be harder to spot.
