Just dropped it off, and the service rep says " Macans normally need new discs at the same time as they are lightweight discs". I tell him that shouldn't need it, as per your comment, he says they will look......
...really hacks me off that basically I don't trust them...
My discs and pads have both worn at approximately the same rate so they are expected to need changing at the same time. Porsche say they allow 2mm of wear on the disc which starts life at 34mm thick on the SD. I'm at just over 28,000 miles at the moment and am told they will need doing soon.
Incodentally, I have PTV+ and my rears are slightly less worn than the fronts but not by much.
I just thought I had better correct this previous post. I was told that my car would need brakes and discs all round soon back in May. Watching the dealer video back, the technician said that the front discs were 0.3mm above limit which works out as 85% worn.
However, I just had my winter wheels put on and a different technician checked the brakes. He measured the front discs at 1.3mm above limit (2mm wear allowed) and the rears at 1.2mm above limit. So 35% wear on the front and 40% wear on the rear. Most of the pads were at 6mm with a 2mm limit.
So the poistion has changed from needing to service all the brakes at 30,000 miles to probably not needing to do it until maybe 60,000 miles! Quite a difference. I may need pads before discs and rears before fronts (maybe due to PTV+).
I am just hoping the second technician has got it right. Next time I will ask to see them being measured myself!
