I'm rebuilding the front end on my Aero RV and am going to rebuild the disc brake calipers and am wondering what I can do to reduce the parasitic drag inherent in braking systems, especially disc brakes.

I'm guessing some of the various materials they use for disc brake pads vary in the amount of drag they induce when the vehicle is running down the road. Does anyone have any data on this? Do ceramic disc brake pads induce less drag on the rotors than say, semi-metallic pads or regular organic pads?

Does anyone know of any specific modifications you can do to disc brake calipers (other than cleaning and lubricating the parts and rebuilding the cylinders) that will make them release more efficiently?

Being a one ton front end these calipers are massive compared to my Saturn. If you jack the wheel off the ground and spin it with your foot, it only turns maybe two revolutions before it stops. That's a serious amount of drag.
