I believe everyone knows the importance of the braking system, because the braking system of semi-trailers affects the safety of truck drivers. So, how should we maintain our braking system in daily truck life?

　　Semi trailers usually have their brake pads and brake drums replaced according to the mileage traveled. The brake pads should be replaced in a timely manner around 30000 kilometers, and of course, it also depends on the specific usage of the cardholders. They should be checked every 10000 kilometers and replaced when they are worn to a certain extent.

　　In daily maintenance, if the brake fluid is lacking for a long time, it is obvious that there is a problem with the brake system. The color of the brake fluid should be checked, and it should not be too dark.

　　If the semi-trailer deviates to both sides when braking, it indicates that the front wheel brakes are not synchronized, and there is a high risk of danger during high-speed driving. Immediately go to the repair shop for brake calibration.

　　It is also crucial to pay attention to the brake system during the running in period of a new car. It is particularly important for a new car to break in during the first 1000 kilometers of driving, and the braking system should try to avoid emergency braking as much as possible. It should also be noted that before stepping on the brake, the clutch should be pressed first. However, after the break in period, it is still necessary to use the method of braking first and then pressing the clutch to extend the service life of the clutch.

　　The above is a brief introduction to the braking system of semi-trailers by the editor, hoping to be helpful to car owners.
