Final answer:
In a 'low drag caliper' design, the disc brake pad return force is enhanced by caliper guide pins. The guide pins reduce friction and drag, allowing the brake pads to return to their initial position more efficiently.
Step-by-step explanation:
In a 'low drag caliper' design, the disc brake pad return force is enhanced by the caliper guide pins. The guide pins are part of the braking system and help to ensure that the brake pads return to their initial position after being pressed against the rotor. By providing a smooth and efficient movement for the brake pads, the guide pins reduce friction and drag, enhancing the return force of the brake pads.
