As i have only had the R a week from a main dealer and was serviced and pre purchase checked out.
Still under warranty .
I know brakes wear .just wondering when a lip is bad.
And been told of the cost of these discs. and main dealer only i think.

Harping on here a bit.ive just had a better look and there is rough gess about 2mil lip.
But looks strange like the edge should be there.if you get my drift.

It’s my understanding that any brake disc should originally be completely flat (no lip). I have also heard of discs being “skimmed” to remove any lip that has formed. The only issue here is that you do need a minimum thickness on any disc for it to be both legal, and more importantly, safe.
Excess lipping can cause brake squealing (other things can cause this too).
Brand new pads should sit (more or less) in the same “groove” that the old pads have worn into the disc, however, the fit is not likely to be perfect, so the edges of the new pads can be worn excessively at first if the discs have noticeable lipping, this can also affect braking, which is one of the reasons it’s wise to break new pads in carefully after first fitting.
So, to answer your question, the disc should be smooth to the edge.

I've just bought new discs and pads for the front of mine. Going to try and get them fitted next week.
