There is a cone behind the piston and it moves with the piston when the foot brake is applied. When the parking brake is operated, the brake lever turns the screw on which it is mounted (it also is an an adjusting screw threaded through an adjusting nut). The nut can't turn because it's splined into the cone.

How do you adjust a parking brake caliper?
To adjust initially, the piston is adjusted outward by turning the nut on the lever or by cranking the lever . This ratchets the caliper piston outward just like using the emergency brake would do. This moves the piston outward taking up that distance between the rotor and the pads.

How do self adjusting brake calipers work?
It works in a very simple fashion. Each time the lever is pulled, enough fluid to move the pistons, and therefore the brake pads, is pushed out of the caliper far enough to contact the brake rotor . As they move out of the piston, they push past the caliper seal.
