I have a 30,000 mile Land Rover Discovery 3. It's 30 months old and was supplied and serviced by the main dealer, the last time in November 2009. It recently developed a horrible squealing noise from the rear nearside wheel on a long journey home from Norwich. I limped in in to the dealer after seven hours and left it with them. After six days with no car they looked at it and said the brake pad was worn and had got hot, fallen apart and damaged the wheel brake disc, with new ones required at £400.

I asked to see the damage. There was only one wheel and one pad on that wheel was really damaged, and the backing plate which the pad is adhered to had corroded so badly it had expanded to four times its width thus pushing the pad constantly against the disc, creating heat, friction, and drag. There was no warning of this except the horrible noise, and all other wheels showing normal wear. How can this happen in such a new car with a make like Land Rover who are supposed to be the best 4x4 in the world? It obviously isn't built even to cope with a British winter. As usual the dealers is telling me "Oh there's no chance we can claim on the warranty". Surely this cant be true?
