well if in an extremely cold evironment the fluid can get "jelly like" so I recommend a special cold-environment brake fluid...have some of this put in there and your problems will probably disappear~_______ https://www.google.com/#q=brake+fluid+for+cold+climates&tbm=shop
ABS motor running when key is turned on, water in brake fluid, Brake master cylinder not releasing pressure, just a few things to check.
