Last month I suddenly started hearing a metalic noise that sounds like
it's coming from the rear wheels. The noise is rythmic and repeated
over and over only when the car is in motion.
The noise is similiar to that of a knife blade being sharpened on a
stone if that make any sense.

I realize that asking about a noise problem on this group is not the
best way to deal with this problem because you can't hear the noise but
I was just wondering if anyone else has encountered this.

Put it on jack stands, give the wheels a spin and look. Inspect your
brakes while you're there.

Ok, I've been meaning to try that. What should I be looking for?

sounds likethe rear brake linings are worn down to almost nothing
 
I put the car on jacks and took the wheels off.Sure enough, when I spun
the right rear wheel I heard that scraping noise. Could worn brake
produce such a noise while the car is moving and the brakes are not
being used? As a matter of fact the noise would stop when the brakes
were pumped when this first started happening. Now the noise happens
either way.
Could it be that the bake pad has broken and is scraping the wheel?
 
More than likely you have worn the brake shoes down to the rivets and they
are beginning to destroy the rear drum(s). The first sound you heard was
designed as a signal to get them looked at. At this point you may no longer
be able to resurface the drums and need to replace them (extra $$).

Hmmmmm $20 bucks to turn each drum or $14.99 each + tax for new ones? No
loss there. :-)
 
To close this thread I took the car to my mechanic. It turn out that
the rear caliper was locked and it was scraping the pads against the
rotors.
I had him do a complete front and rear brake job and it breaks down
like this.
Parts and labor for complete front brake job and resurface rotors.
Clean and bleed front calipers.....$245

Parts and labor for complete rear brake job and installed new rear
rotors and adjust emergency brake....$245

2 new rotors...$91 ea.
brake fluid cleaner ...$15

I new caliper complete...$219

Hope I didn't get ripped off.

Thanks for all your replies.
 
The rotors were pretty high for sure (OEM dealership price?) and I
wouldnt "turn" anything these days. Everything else seems to be in the
upper medium. 15 dollar brake fluid cleaner? Clean brake fluid I'm
guessing. It could of been done for less certainly but I dont think you
were ripped off so long as they did a good job and back up their work.
 
Yeah, he said that the brakes were good for 40,000 miles. Everything
seems to be4 working ok.
 
Bla,

From the content of the post, I assumed he was having the work done and not
doing it himself. Most dealerships/service garages charge a whole lot more
(as the OP found out) for new drums/discs (I assumed they were drum brakes
when the later post makes it clear they were discs, but the bottom line is
the same ... just replacing rotors instead of drums) then for resurfacing.

On the $15 drums, these are the "generic white box specials" made in China
and, in my opinion, of questionable quality. I pay a little more and use US
made NAPA drums and rotors. For me, I do the work myself and resurface
them ($15 ea) every other change before replacing the following time.

I am not trying to fault your method since it works for you ... just trying
to explain my original reply to his post.
