👉 The wheels fluid, also known as wheel oil or brake fluid, is a vital component in automotive systems, primarily responsible for lubricating the moving parts of the wheels and brake system. It helps reduce friction between the wheel hubs and the axles, ensuring smooth rotation and minimizing wear on brake pads and rotors. Additionally, it transfers heat generated by the friction process to the surrounding environment, maintaining optimal operating temperatures. This fluid also acts as a sealant, preventing contaminants like dirt and water from entering the brake system. There are different types of wheels fluid formulations, including mineral oil-based and synthetic oils, each designed for specific vehicle requirements and operating conditions.
