Light Rust or Grime on Brake Pads ?

[MadMax]

It's nothing to worry about, your rotors are bare metal and a little surface rust will happen when they get wet. In extreme conditions, your brakes can even "lock up" a little requiring a bit of forward movement to break free (this used to happen to my Passat in Belgium). But for the most part, they will clear up as soon as you use your brakes.

I travel a lot for work and if we get any rain while I am gone, my brakes usually are covered in surface rust when I get back. I just returned from being gone a week, and this is what mine look like...



It's nothing to worry about, it'll clear after a mile or so of driving and there is no advantage to trying to clean it off beforehand...
