Final answer:
The purpose of brake calipers in a disc brake system is to apply pressure to the brake pads, creating friction against the rotating rotor and slowing down or stopping the wheel rotation. The calipers house the brake pads and are operated by hydraulic fluid, which causes them to squeeze the pads against the rotor. Brake calipers are designed to be strong, durable, and heat-resistant.
Step-by-step explanation:
The purpose of the brake calipers in a disc brake system is to apply pressure to the brake pads, which in turn creates friction against the rotating brake rotor. This friction slows down or stops the rotation of the wheel, bringing the vehicle to a halt. The brake caliper houses the brake pads and is responsible for squeezing them against the rotor.
When the brake pedal is pressed, hydraulic fluid is sent from the master cylinder to the brake calipers. This fluid pressure causes the pistons within the calipers to move, forcing the brake pads to make contact with the rotor, resulting in the braking action. The calipers are designed to be strong, durable, and heat-resistant in order to handle the high temperatures generated during braking.
