Do the aftermarket calipers release/drag less than the original units? I have good brakes, but have always fought the pads dragging a tag more than what I *thought* they should. Same with the rear...even with the adjusters backed all the way off, there seems like a touch of drag?? If I went 4 wheel discs, wouldn't I be fighting the dragging pads as with the fronts???
