Rotation and vibration of the wheel helps to retract the piston, disc brakes are designed to rub all the time.christo is right they are un efficent in that respect........run the bike around for a few miles without using the front brake, pull up using the rear brake only....then try spinning the front wheel, it will be easier to spin.....go on try itÂ

One, is never going to be enough.....
