The brake hose is replaced every 30000 to 60000 kilometers or every three years. There is no fixed time and mileage regulation for the brake hose, and it needs to be replaced whenever there is aging or leakage. To ensure that the vehicle's braking system maintains good working performance and ensures safety and reliability, brake hoses need to be regularly inspected for aging and leakage of cuts and scratches. The brake hose is a component in the automotive braking system, whose main function is to transmit the braking medium in the automotive braking process, ensuring that the braking force is transmitted to the automotive brake shoes or calipers to generate braking force, thereby making braking effective at all times.
