Well you've lost me with the DSC / DTC thing causing brake wear here.
I thought DSC/DTC functions were releasing the brakes when you were too heavy on them, stopping the wheels locking up and so preventing a skid.
That suggests to me, its saving brake pads, not wearing them?
Can someone explain why it would cause extra wear?
