Are they marks or grooves ? They could be warped it could be transferJust done a 200 mile round trip , looked around my car and spotted this on front n/s View attachment 252053
Think I'll pop into the dealer with it , and see what they say , never had a disc go like this before.
Booked in for Tuesday, will let you know how I get on.Do it before 6 months or 6000 miles as that’s how long it’s warranted for.
Had a closer look at mine after 3k miles. So yea something's up with yoursThe rusty bits i would say normal but a bit early for it to rust? The lines on the brake disc, err i did not notice on mine, and I've done over 3k miles now, will check tomorrow but i don't remember any lines
