I believe the Formula Dynamics pads do not have a provision for the electrical brake wear sensor. This is not a comment on the desirability of the pads, just posted because folks ought to know this when making a buying decision. Please correct me if I'm wrong. Aside from that, I've seen very favorable reports on them here but have no first hand experience.
True. I'm not aware of a pad at the moment that allows for this besides the OE Pads. You can still finesse it to work however it takes some doing. Most people simply terminate the sensor so that it reports that your pads are in good shape and watch them manually. Of course they still have the noise indicators when the pads wear down. Most people change pads before they get low anyway.
