is that normal? it sounds like the brakes are lightly being applied, even when i'm totally off of them. is there such a thing as the distance between the pads and rotor being too small?

How much pad do you have left? Does the grinding noise get louder when you brake?

i've been reading the archives a bit, and I definitely have brake chirp (when you hit a bump, and you're not applying the brakes) AND when applying light braking pressure, i hear constant squeaking, like running your nails along the chalkboard.

I'm going to the dealer tomorrow. Are the 2 problems the same thing? i found the TSB on brakes, would that fix both problems?

The shield behind the rotor has been bent, and is rubbing on the rotor. It's a hideous sound, and is a 2 minute fix.

On old Coupe Quattro, I had a rock thrown up into the brakes and lodge between the rotor and brake shield. Similar hideous sound that varied with car speed.

So, turn off the computer, remove a wheel, and do some careful investigation. By rotating the hub by hand you ought to be able to pinpoint the location.
