Crap, a noise

Go figure - two weeks before the Big Meet, my car starts making noises.

From the front left, during tight right-hand turns, I can once in awhile hear a really, really low-pitched squealing. After hearing it, I took the car to an empty parking lot and started swerving around with the windows down. While the howl was absent, I did hear a loud scraping noise.

I suspect that the front caliper is sticking. I may not have greased the slides the last time I took it apart about a month ago.

Any other ideas?

Does it change or go away when you apply the brakes?

Significant Technical Input
The backing plate may be a touch too close to the rotor. When turning the rotor may flex just enough to contact the plate. Also another item to investigate are the pad shims, they can slip and touch the rotor also, but generally they'll make noise all the time, not just while turning.

That's a really good question - I'll find out tonight.

I don't suspect the backing plate, because when it squeals, it's a REALLY substantial noise that I hear through the car.

I may just replace the pads. It's been 18 months and just getting a new set with new shims couldn't hurt.
