It must rotate the piston when applied, but that's only in small increments of degrees each time. The replacement of the pads will be many rotations i assume. I'm not worried, the lip of the seal in the smooth bore should be fine with rotations.
I keep thinking in terms of hydraulic actuation, in and out, rather than a small electric motor turning things, funny.
