When I brake, I hear a grinding noise when the car is coming to a stop i.e. once under 10mph or so. I don't hear the grinding at higher speeds, just when going very slow. I was assuming it's a brake thing as the noise starts/stops if I lift my foot on/off the brakes however all pads are relatively new and all discs have been done within last couple of years. The garage I use said no sign of pads/discs rubbing, I've not however taken it for a second opinion. Could it be something more serious e.g. a wheel bearing that is being caused to grind when brakes are applied? I 'think' the noise is coming from the rear however difficult to know for sure. Car's an 08 plate, FR TDi.
