A while back, I upgraded the front brakes on my Seville. The calipers are the same dual piston ones that the DTS uses. I used EBC RedStuff pads and their Ultimax slotted rotors, which I also had before the upgrade. The pads that fit the stock calipers had the channel in them for the pad wear indicators, the new pads for the dual piston calipers do not. Does the DTS just not have that feature, or does EBC just not cut the groove.
It really doesn't bother me, and I'm enjoying the upgrade, but I was just curious.
