Does a car need brake maintenance?

Car needs brake maintenance. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transport or machinery. The purpose of braking is to slow down and stop the vehicle. Its principle is the process of energy conversion that converts the kinetic energy of the vehicle into thermal energy through friction. Brake system maintenance time: disc front wheels about 30,000 kilometers, disc rear wheels about 60,000 kilometers, drum brakes about 100,000 kilometers; The brake system is the key to safety, and the replacement cycle is only a rough reference. The focus is on the thickness, and early inspection is the most secure; Brake fluid should be replaced after driving about 60,000 kilometers. The necessity of brake maintenance: Brake fluid has strong water absorption. When a new car runs for one year, the brake fluid will absorb about 2% of water, and the water content can reach 3% in 18 months. This water is enough to reduce the boiling point of the brake by 25%. The lower the boiling point of the brake fluid, the easier it is to generate bubbles, forming air resistance, causing brake failure or even failure; At the same time, the brake system is greatly affected by the working environment. Once there is a problem, the car will be very dangerous and become uncontrollable. Therefore, it is necessary to clean the attachments and sludge on the surface of the brake system, strengthen the lubrication of the wheel cylinders and guide pins, and eliminate brake noise to ensure driving safety.
