How to maintain the semi trailer brake system?

When winter comes, some card friends report that their trailers are slow to brake due to the weather cooling, and the relay valve is frozen, causing the brakes to lock up, the semi trailer brake system which is a great safety hazard. The semi trailer manufacturer will briefly introduce how to maintain the brake system.

With the arrival of winter, the lower the temperature, the harder the sealing ring or the cushion. After the wind and rain in summer, the sealing performance of the rubber ring is getting worse and worse, especially the pipe joint above the axle. the semi trailer brake system,The low temperature in winter will cause the sealing The pipe joint shrinks, and the sealing performance is poor and the air leaks. The trailer manufacturer recommends that you must check the sealing of each joint in the gas path before you leave the car in the morning. If there is air leakage, tighten it or reinstall it in time.

trailer manufacturers recommend regular replacement of brake oil; brake oil is an oil that has a great impact on the brake system in addition to brake pads. Some maintenance focus of brake fluid is to ensure that it does not deteriorate, especially to prevent the infiltration of water. The brake fluid should be changed every 50,000 kilometers. the semi trailer brake system,If you drive in wet areas for a long time, the oil change interval should be shortened appropriately.

Check the gas line joints: In winter, the temperature is low, and the sealing ring or cushion is relatively hard, which can easily cause the joints of the sealing pipe to shrink. Therefore, before leaving the car in the morning, be sure to check the sealing of each joint of the gas line. Install.

Check the main vehicle drying tank: Check the main vehicle dryer tank to ensure that the main vehicle air source is dry and free of moisture. the semi trailer brake system,Since the drying tank is an air filter, the longer it is used, the easier it will lose its filtering effect on the residual water vapor in the compressed air, resulting in the accumulation of water in the pipeline and the valve body, which will affect the normal use of the brake.

Drain water during main and trailer periods: In winter, the temperature is mostly below zero, and the gas is prone to water droplets. Therefore, the main car and trailer air storage tanks need to be drained regularly to ensure the dry gas used in the brakes. the semi trailer brake system,If the water is not released in time, the damp gas inside the air storage cylinder will easily enter the valve body. When the temperature is lower than zero, it will freeze, causing the piston to be stuck and affecting the braking performance.

ABS maintenance: ABS is connected to multiple sensor joints, and its function is to transmit the brake system signal, so that the ABS system can exert the best braking force and frequency. Therefore, it is necessary to do a good job in the inspection and maintenance of each sensor joint. At the same time, the semi trailer brake system,the ABS ring gear should be removed and cleaned regularly to ensure that the sensor signal of the ring gear and the probe is good, and the joint is free of putty.

In order to ensure the stable braking performance of the trailer, in addition to the daily maintenance and maintenance of the braking system, the semi trailer brake system,it is also very important to choose an axle with good quality and stable performance. The higher the quality of the axle, the more sensitive and reliable its braking performance, which can provide a guarantee for driving safety in severe cold weather.
