I have this weird problem with my emergency brake. This only happens on certain conditions but are repeatable. When it is raining and only when I back into my driveway or a parking spot my truck sticks after using the emergency brake. It feels like the brake has released but when I try to accelerate it goes no where then all of a sudden it lets go. Like I said, this only happens when it rains and if I back into a spot. If I pull into a spot forward there are no problems. Does any one have any ideas about this weird problem or has any one experienced it too? Thanks for your help.
