In this video, we see a close-up view of a car's brake system. The camera focuses on the brake rotor, which is a round metal disc that is attached to the wheel of the car. The rotor is being held in place by several bolts, and there is a brake caliper on the side of the rotor. The brake caliper is a metal part that holds the brake pads, which come into contact with the rotor to slow down the wheel. The person in the video is pointing to the brake rotor and the brake caliper, likely explaining how the brake system works. The video does not show the brake pads or the brake fluid, but these are also important components of the brake system. The video is shot in a well-lit environment, and the camera is steady, allowing for a clear view of the brake system.
