Metal on Metal sound?
 

I have a 94 honda civic si.. All of a sudden I have a high pitched metal on metal grinding noise when I back up, and when I drive it is still there a bit, but not near as bad. What can this be?

More specifics? Where is the sound coming from? Does it happen when your going slower or faster? Just a grinding noise, or is it like banging too?

Sorry... definately coming from the rear.. have not pulled the whell off to check brakes yet.. no banging sounds.. just a grinding type sound..

i think it's time for some power slots! i dunno it should be the brakes.

I'd guess brakes. When's the last time you changed the pads?

mine do that all the time, see if the vaccum plate is a little bent on any of the brakes, could be rubbing nothing seroius though.

Are your pads worn down to the squeelers?

Chances are it's that since I had exactly the same problem with my old pads on my mazda, when I backed up they squelled like hell.

i say the pads are toast
