I have them on my ML and the only complaint is that they can be a bit noisy
during light braking. After about 10K miles, I did remove them and "knock
them down". This temporarily eliminated any squealing, and also
significantly improved braking performance. I was also quite impressed with
how well they are wearing as compared to MBZ OEM's.
It seems that this could be a possibility given that they are harder than
OEM's. I have over 50K on my original rotors (over 30K of that with the
Rotex Pads), but I have not bothered to measure them. I have no vibration
to make me expect that they are wearing too thin. I will check them at the
next pad change (which looks like it will be at least another 20K miles).
My guess is that then, with nearly 75K miles of wear, it will be time to
replace them regardless of the hardness of the pads.
