My new 2013 civic sedan does something that I'm not sure is normal; when the car is warmed up, usually on a drive longer than 10 miles, the brake pedal is no longer completely smooth when depressed. It makes a rubbery creaking sound, almost as if the pedal mechanism isn't oiled properly or something. I can also feel a bit of roughness in the action of the pedal when it does this. However, this does not affect the brake operation at all, it's simply a problem with the pedal feeling a little rough and creaking after the car's warmed up on a longer drive. Has anyone else experienced this? I'm wondering if I should take it into honda. The car has only about 650 miles on it.
