That's right, I think I've a stone in my brakes but I'm not certain. These noises only occur at low speeds.
When first pulling away after it's been sat for some time there is a rotating squeak/rubbing noise. This stops as I accelerate. When in traffic at low speeds and the steering wheel slightly clockwise (that's turning right!) there is a rubbing noise as I brake. Not rotating just a constant rubbing/grinding noise. It's not loud.
I've tried the old reverse, forward, reverse technique but nothing changes. Any ideas short of taking it to the garage? It was serviced the other day.
