Brake calipers play a crucial role in the braking system by clamping the brake pads onto the rotors. When the brake pedal is pressed, hydraulic pressure is generated through the brake lines, which causes the calipers to compress the brake pads against the spinning rotors. This contact generates friction, which slows down or stops the vehicle. The effectiveness of the braking system heavily relies on the calipers' ability to apply sufficient force to the brake pads, ensuring consistent and reliable stopping power.

Other options, while related to vehicular systems, do not pertain to the primary function of brake calipers. For instance, adjusting brake fluid levels is managed through the master cylinder and fluid reservoirs, rather than the calipers. Monitoring tire temperatures is unrelated to braking and typically involves other systems or sensors. Providing electrical signals to the brake lights is a function of the vehicle’s electrical system, specifically the brake light switch, and does not involve the mechanics of the calipers.
