Renault told me my rear discs and pads were heavily worn at 12,000 miles. I sold it on 57,000 and two track days, with the original equipment still fitted. Every Renault dealer I used was run by arseholes. I'd certainly never go to one for an MOT. That's just my experience though.
renault birmingham told one of my punters his front brakes were 70% worn when they were less than 24hours old! (brown bear on here)
i was seriously shocked by that one!
