I purchased a used 2013 Honda Jazz with 42,000 miles on the clock. I did notice corrosion on the all the brake discs at the time and the rears were quite heavily corroded. The comment by the salesman at the Honda dealer was that it was just surface rust as the vehicle had been standing for a long time and would clean off.

The front discs did clean off but upon checking the tyre pressures yesterday, I noticed that there was a lot less contact on the rear discs and barely 0.5-inch band on the nearside disc. I took it to a local Honda dealer in Wolverhampton and they confirmed that it would need new rear discs and brake pads. How would you advise that I approach selling dealer with this issue?
