From outside the car as it goes by at a slow speed, you can hear a rubbing sound that sounds like a warped rotor tapping against the brake pad as the wheel turns. It's not a squeak - it just sounds like a slight rub of pad against rotor. Also, it's not constant. It sounds like it rubs in one particular spot, so there is a pulsing effect as the wheel turns (rub-rub-rub-rub-etc.)
The strange thing is that you cannot hear it at all from inside the car and you cannot feel anything but a nice solid brake feel. If it was actually a warped rotor, wouldn't it be felt as you brake?
I had the car in service for something unrelated and asked them to look at it. Of course, when I picked up my car, all service people had left and the note said they were not able to recreate it. I think my SA forgot to put that you can only hear it from outside the car!
Now, I'm trying to get some info so I'm ready when I go back in - thanks for any help.

i have the same problem... the thing is that you only hear it when driving very slowly.. its like the braking squek but on every turn, and your not breaking..
im not sure if it continues once the brakes are hot but i always notice it when i start the car and reverse or start driving slowly..
and i cant feel anything wrong..no vibration.. just the sound ill check if the sound continues once the brakes worm up, tomorow.

freed0m has the same symptom.
Tried to find a post from "freed0m" and couldn't find it. Maybe I'm just missing it. I'll PM and if there is useful info one of us will post.

Bingo! I think zen is right on... The 'wub, wub, wub' sounds started after I got my wheels reinstalled from painting... I was told to make sure that I get the lugs tightened after driving around for a couple of weeks. Ofcourse, I haven't done it yet. I'll swing by the shop to get it them tighten tomorrow and report back ASAP

Make sure the lugs are tightened to the proper torque and that one of them is not tighted too much. sometimes the rotor gets warped by uneven torque.

I think that one of the handbrake pads (jaw) has been broken. I'm 99% sure about it.
Here is a pic on that issue.

Thanks for the responses guys. I'll check the torque on my lugs. Also, nicke60gre, I didn't even know this could happen. I'll check into that as well.
If anyone else has any ideas, please post. I should have my car in the shop this week and will be armed with info. I'll post the outcome, of course.
