after my front discs had corroded away to nothing on my 53plate cup 14'000miles I replaced them with brembo HC discs and greenstuff pads, then I thought right the rears are humped also but I don't want to have to replace these out of my pocket as they are expensive.So off I go to the dealers,they looked and said yes they are corroded!!!! (no s**t) and this was usually a warranty issue but because the car had only done 14'500miles they would not do it!!!! but if the car had done at least 7500miles per year they would replace them. So basically they are saying I have not used the car enough even tho it is used everyday altho not many miles....................Renault UK are getting a ring tommorow.
