The brake system is crucial to the performance of the car. The brake system of a small truck mainly uses brake oil to transmit the braking force, while the heavy truck uses a pneumatic brake system. The two should use different maintenance methods. For cars with oil circuit brakes, check the brake oil level before driving.
If the oil level drops, check the brake oil circuit immediately for leaks. Brake oil absorbs moisture in the air and will become ineffective over time. It should be replaced once a year. For pneumatic brake systems, it is important to drain the accumulated water from the system and replace the dryer regularly. The water in the pneumatic system will corrode the pipeline and affect the brakes, and in severe cases, it may even cause the brake system to malfunction. In addition, it is also necessary to frequently check the working condition of the air pump and the wear of the air pump belt and replace it in time.
