How do you retract a caliper?

To retract a caliper, first, ensure the brake system is depressurized if you're working on a brake caliper. Use a caliper tool or a C-clamp to gently push the piston back into the caliper housing. If the caliper has a screw-type mechanism, turn the screw clockwise until the piston is fully retracted. Once retracted, check for smooth movement and reassemble any components as needed.
