A&Q about 350Z
Q:
hi
it was kinda cold n humid the other morning
as I slowly drove away, a rough rubbing sound was heard, kinda high pitched
no brakes were applied......what would cause that, jus driving???
BTW: 2005 civic 4 door
A:
Could be rusty rotors. The pads always drag a little and if there was some rust on the rotors it might cause the noise you were hearing. Did it go away after a few applications of the brakes?
A:
ya, after a bit it went away
but this was a sound that was being heard without applying the brakes
as even though the car is free moving, there was something rubbing
i'm probally worrying about nothing
A:
The brake pads are always dragging on the rotors a little. Its just that they don't normally make a sound because the rotor is relatively smooth. When you get flash rust on the rotors, those dragging pads sound a lot worse.
