Scraping sound when not scraping

Jordo! · 11-17-2014, 10:50 AM

Check the the brakes -- I seem to recall that there is a thin metal dust/heat shield (?) that can scrape the caliper as the wheel rotates and needs to be adjusted like a mm or so to avoid light contact.

Another possibility is the sliding pins for the calipers

I think there were TSB's for the G37 on these issue, and I had the first one on my Z.

Finally, there could be a small pebble trapped in the caliper that is scraping.

I've gotten that several times with a damn pebble. A short, quick acceleration usually takes care of that.

Oh. And if you hit a deep puddle of water at speed, there is a chance you could bend the shield underr the driveshaft causing it to make contact and it is more pronounced when engine braking. You'll have to bend the shield back. Happened to me last spring. But, that's actually scraping I suppose. Not sure how many people have ever dealt with that. I might be the only one. But it sounds a lot like a rotor/wheel issue. Kinda scary.
