Help. Only has 6k miles on the clock, and upon braking the noise seems to get louder. Does anyone have similar experience? I rarely valet my car, but one time in San Diego Hilton, I did valet, but this noise problem started 2 months after my SD trip.

Have you looked at your rotors. Are they rusted. Are these PCCB or iron?

Edgy01

Occasionally something will get wedged in between a rotor and a caliper's pad. Drive it aggressively for about ten miles and then go back and try to locate the noise. If that doesn't shake it loose, get it up on jack stands where you can turn the offending wheel with the engine off, and listen closer to where the problem may lie.

I have the same problem, started after the winter wheels were put on, brought it in once, told "normal ABS" noise, BS
when I bring it back to have the wheels changed, i will have them look again, i tried hard braking (100 to 0) ad this did not help

Like Edgy said, things can get caught in between the calaper and rotor. Look for a small rock it's the most common (if you have driven thru a freshly black-top area those little oily rock stick into the oddest places).

Had that when first got my car.Freaked out and then it went away forever.Pebble getting caught sounds right.

I get this once in a while too. Doesn't seem to last . It does seem to me it was after the winters were put on.

This doesn't bother me as much as after a winter car wash, parking the car then going out in a couple of days and the wheels feel "stuck". Sometimes backing up will "unstick" them

I had this happen on my 996 following a DE event. I still haven't addressed the issue.

Thanks for your valuable suggestion as always, Dan. I will give it a try and post the result.
Cheers

I just found that the grinding noise happens upon turning of the wheel at a slow speed, so this may not be related to brakes ???

any change this is while turning wheel, in reverse, at low speed? if so, this figured out to be normal from another post - multiple people experienced this when pulling out of tight parking spaces / garages.

Yes, this i what my 997s does, last time I had my dealer check this, he called it nomal but it was not there the first 18 months, started after winter wheels put on
