The disc brake bridge is a widely used vehicle component in passenger cars, which relies on the caliper to clamp the brake disc and generate friction to achieve braking. Due to the metal blocks used in its braking components being disc-shaped, it is also called a disc axle.

In recent years, with the mandatory promotion of regulations and the influence of industry trends, the application of disc brake bridges in commercial vehicles has been increasing. With its advantages such as light weight, sensitive response, smooth braking, good heat dissipation, strong resistance to water attenuation, and thermal attenuation, it has gradually become outstanding.

For car owners who are accustomed to using drum brake bridges, even if they are extremely good, they still have doubts about the load-bearing capacity of the disc brakes and feel that buying goods may not be very reliable.

Objectively speaking, such concerns are not unreasonable, after all, compared to the drum brake bridge, the structural design of the disc brake does appear relatively "thin". Can a car model like a three axle fence or a three axle warehouse grille still carry goods like before with a disc brake bridge?

In fact, everyone is aware of one fact: the reason why the disc brake bridge is promoted is not because it has good load-bearing and can handle more cargo, but because it has various advantages, and even because it cannot handle overload, it has been legally implemented.

Taking the most widely covered three axle fence and warehouse gate vehicles in the market as an example, although these models have a high inventory, their safety technology is poor, and the transported goods are mostly low value-added products. In order to earn more freight, car owners often transport according to the maximum limit of the approved load, and even ignore traffic regulations for overloading and exceeding the limit. This not only affects traffic safety and damages the road surface, but also hinders the long-term development of the transportation market. Forcing it to install disc brakes and suspension can not only improve its driving safety, but also to some extent reduce the possibility of overloading and exceeding the limit.

In addition, the disc brake bridges in the market are generally sold by tonnage, such as the conventional 13T model, which is consistent with the bearing range of 13T drum brake, as long as it does not exceed this range, there will be basically no problems. Of course, the premise is that the quality of the selected disc brake bridge itself is strictly up to the standard, and it can not be shoddily manufactured. Secondly, the problem of working conditions is that the disc brake bridge is suitable for the field of standard load transportation, and the transportation of some precision instruments, dangerous chemicals, green links, fragile and vulnerable goods and valuables is also more suitable for the disc brake bridge.

So, in the process of using the disc brake bridge, does it need to adjust the brake clearance as often as when using the drum brake bridge? The answer is No. Because the disc brake bridge is generally equipped with a self adjusting arm, it usually does not need to be adjusted manually. Of course, there are two concepts: no need to "adjust frequently" and no need to adjust. If the owner has just changed the brake components or just finished the wheel end maintenance, it is suggested to adjust manually, which may lead to the situation of towing brake.

How does the disc brake bridge adjust the brake clearance? The method is simple:

Locate the slack adjusters;

Tighten it in the tightening direction with a special wrench, and the wheel end will not turn at this time;

Then screw the bolt back three times in the direction of loosening, and one time will make a "Da" sound. After three sounds, the brake clearance will be adjusted.

When choosing the disc brake bridge, we should remember to compare the goods. Darong group has specialized in producing all kinds of trailer rear bridges for 20 years. Its disc brake bridge is made of 20 Mn2 high-strength alloy seamless steel pipe, which ensures strength, toughness and lightweight from raw materials. At the same time, it is equipped with more than ten processes, such as one-piece heat treatment forming technology, three hole boring finishing, medium frequency induction treatment and so on. The finished products have been tested before leaving the factory to ensure that the quality meets the standard, Stable and reliable.
