It's a lever & cam thing in the Z for the parking brakes.  The
manual cable pulls on a lever which on/outside the caliper
body/assembly.  This lever rotates a ~small cam (on axis) ~inside
that assembly.  This cam pushes a rod, and that in turn moves the
piston & brake pad.  Got a couple of misc parts there too, eg. the
return springs and etc.

For normal braking, the hydraulic fluid pushes on the same piston
as mentioned above; so, it's just one piston per brake/wheel.
