Well for the past 2 days my ebrake light is flashing on and off depending on how I use my brakes. I see the brake fluid resivoir is on fill, is this all it is? Just add brake fluid? Or is it actually my e-brake somewhat stuck? The reason I ask is that its been in the negative temps for the last week and I know e-brakes can get stuck, when cold. Just looking for confirmation really, pretty sure I'm right, and a search didn't pull up anything.
