sorry about another novice question.
The other day I notice this grrrrrrrrrr noise when coming to a stop. The weriod thing is it only does it after the truck sits all night or all day.
I heard it the other day for the first time. Just a little bit at the first stop sign in my neighborhood and just a little when starting home from work. Only at the first or second stop.
This morning was worse.
I know rotors will form rust after setting for many days but not in hours.
Again it does it only when it is cold or hasn't been driven. After driving a few miles with a several stops it seems to go away.
