In the video, a person is seen using a wrench to adjust a part of a car. The person's hands are covered in grease, indicating that they have been working on the car for some time. The car part appears to be a brake caliper, which is a crucial component for stopping the vehicle. The person is turning the wrench in a clockwise direction, which suggests that they are either tightening or loosening the brake caliper. The background is blurred, but it seems to be a garage or a workshop, with various tools and equipment visible. The lighting is dim, and the focus is on the person's hands and the brake caliper.
