Guys - this is a weird one...

I have a grinding that is coming from the driver's side wheel bearing area...

I have changed the bearings twice with no real change in the sound...it sounds like sandpaper on a piece of wood...

If you listen close from 0:09 to 0:13 you can hear it---its sounds like someone sanding a block of wood...

Is the rotor full of rust? Is ther a rock stuck in it? I have tried adjusting everything - even the backing plate for the brake...the sound wont go away...

I also have driven with this sound now for a couple of thousand miles...nothing has broken, nothing has worn and the van is striaght, smooth and sure footed all the way to 90MPH...

I am stumped...I do have 210k miles - is the spindle worn out?

Thanks

Are you sure it's coming from the front brake?? If the spindle was worn, you would get a clunking sound, and weird steering.....

 

You could jack up the wheel a little bit and have someone spin it by hand while you locate the sound. A mechanics stethoscope might help.
If I had to take a guess without looking at it, I'd put my money on the caliper slide shims rubbing on the rotor. It's very hard to notice and doesn't even leave a noticeable rub mark on the rotor.
If this is the case, you can safely ignore it and it will eventually subside as the shims become worn enough to clear the rotor.
You can tap the shims by hand which will alleviate the sound until after a few brake applications when they will slide into the rotor face again.

 

A bent backing plate hitting the high spot on the rotor will make that sound. Also, remove the wheel and the caliper, then spin the rotor...is the sound still there or gone?
