anyone else experience this? Brake Squeal?

[Brandon002]

The past few days we got hit with the good old polar vortex again.

At first my brakes started to squeak like crazy when turning and braking at low speeds, today they started to squeal while braking gradually in a straight line as well.

My pads and rotors at all four corners are OE spec, have only around 3k miles on them. They do not appear to have any excessive or uneven wear.

Just wondering if anyone else has experienced this? Maybe the excessive cold, salt, snow has cleared any anti squeal grease off the brakes? Dirty?

I'm going to pull the wheels off and give a closer look tomorrow, just wondering before hand if anyone has dealt with this and if there are any specific areas to look at? Never had this happen before on any of my BMW's.
