Brake Caliper: Description and Operation
Front
Fig. 1 Exploded View Of Delco-Moraine 3242 Series Dual Piston Caliper
This dual piston sliding caliper, Fig. 1, is comprised of two interconnected bores and is attached to a mounting bracket with two mounting bolts.
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.
