Fig. 1 Exploded View Of AC-Delco 3242 Series Dual Piston Caliper.:

DESCRIPTION
This dual piston sliding caliper, Fig. 1, is comprised of two interconnected bores and is attached to a mounting bracket with two mounting bolts.

OPERATION
Hydraulic pressure acting on the bottom of the caliper bores forces the pistons outward, enabling the caliper to slide inward, thereby clamping the brake shoes against the rotor.
