Whilst driving a short distance about 1-2miles or so from stationery there was a loud noice from my passengers side rear wheel every time I braked. It was a persistent sound but was intermittent like when you have a stone in the tyre but of course much more loud. I was driving around country roads (single carriage way type in the middle on nowhere) so I wasn't able to get out and have a look for a couple of miles by which time it seemed to stop.

After that everything seemed OK (have driven about 150miles home).

Any ideas what it could be and should I get it checked out by the dealer (the car has only done 2500 miles).

possibly rust on that brake disc , caused by the rain ? although i'vejust seen your location and you may not have had the rain we've had op north

It could have been dirt/mud or grit between pad and disc which has now cleared itself.

Have a look at the discs and see if any of them show any score marks.

I think it unlikely to be rust caused by rain as it only happened after travelling about 50 miles of driving OK and happened after driving in the countryside (nr cirencester) and stopping. I'm inclined to think maybe in was grit or something as it did clear itself after some further breaking and a couple of miles and then everything was OK for the next 150 miles - quite worrying at the time as we didn't really know where we were, the roads were single track and we were someway from the main road.

I have the new Ambience estate and have had the same problem 4 times what happens is grit or chippings get wegded in between the disk and the back plate the last time it happened i had to take it back to the dealers and they had to remove the caliper to remove a small stone

Is this a problem with skodas in general - I have never experienced this before in over 250k miles of driving other cars.

Does it cause any damage to the brakes/wheels? Should I have it looked at my the dealer as the car is only 3m old?

I have had the problem occur on several makes of cars over many years. However I am a high mileage driver and live down a country lane with grit and stones in abundance. My usual cure is to reverse the car which pulls the grit back out and is nearly always successful.

Had this with another make of car. A stone got caught in the ABS sensor ring, it took the tip clean off the sensor which caused the power steering to be intermittent with all sorts of warning lights on the dash.
