Grinding sound
I hear a short grinding (or rubbing ) sound everytime I start the car and drive forward for about the first 3 feet.
Sounds like it is coming from the rear.
Don't hear while driving only when I first drive off.
Anybody with any answers??
TIA

Re: Grinding sound (jabez)
My guess would be rust on the brake rotor. Before driving away, check rear rotors for rust on them. It should wear off quickly.
When mine sits for a while, that will happen.

You may be hearing the ABS system doing it's self test. This happens every key cycle as soon as you hit 3 mph. It makes a kind of grinding type noise and it really suprised me the first time I heard it.

Re: Grinding sound (Steel Blue 91)
I always heard a "groan" on my '92 (ABS). Could this be from the emergency brake pads? They might be slightly rubbing enough (possibly a worn out area on the pad(s)) when you first roll the car forward.
Another possiblity: Rotors could be warped. Do you have a "wobbling effect" when you apply the brakes driving?
Any grinding with a brake system is usually a sign of something worn down.
