Once there is a problem with the trailer’s suspension system, it may cause uneven load distribution on the three axles. When the brake tire of the axle with a small load-bearing capacity is locked, the other tires that are not locked will also be actively reduced by the ABS system. As a result, the braking performance of the entire vehicle becomes very poor. Therefore, if ABS is to work, a suspension system in good condition is essential.
The suspension system is also relatively simple to repair. Just replace the balance beam and axle pin with new parts. It should be noted that the bracket bearing hole is also worn, so it needs to be cut off with gas welding and a new bearing hole is welded.
ABS is a very complex system. If you want it to work well, you need an excellent supporting environment. So when your ABS system has problems and the performance deteriorates, you might as well check whether there is a problem with the suspension system.
