hopefully ive uploaded a picture of my front disc, it looks initially like watermarks but its not , im not sure what it is hence why im posting to gain your thoughts , best theory so far is its age related marks on one disc only but both sides of that disc and only the central holes and marks are clearly centrifugal in nature , braking is as powerful as always no drop of in performance and there is nothing to feel ,cant detect any deformation , i actually mostly removed the marks with 400 wet n dry took it for an hours spin, in the dry, the marks are back again following that. bike has only done 32k miles and im not a heavy breaker by nature but i didnt have the bike from new but it only had 16 k when i got it so ive done half of those miles , theres no splits or cracking around any of the holes so there not stress marks , but what the cause is i cant figure?
