Picking up stones in brakes?

[lunalupi]

I'm hoping someone can suggest why this is happening and any way to prevent it?

Today the Arosa got another stone stuck somewhere behind the FNS brake disk, which pushed something against it and gave off a really nasty metallic screech.
I've had this happen at least three times now in the last couple of years, and every time it happens I have to jack the car up, spin and wiggle the wheel while prodding things behind it until the stone comes pinging out and I can carry on my way.

I was just wondering if this is normal or is there something about that wheel which might be catching stones where it shouldn't?

I had this happen in the navara last year. I think reversing dislodged it.

Happens on Skoda Fabias, VW Lupos as well. VAG character eh!!!!!

you should have a dust cover plate that goes bedind the disc. i had to take it off my ibiza when i fitted the brembos but never had any problems wiv stones getting in them.
