With the development of the automotive industry, the function of the brake adjustment arm as an important component to ensure driving safety is receiving increasing attention.

At present, there are mainly two control methods for brake adjustment arms, one is manual adjustment arm, and the other is automatic adjustment arm. There are significant differences in functionality between the two, with the advantage of automatic arm adjustment being even more apparent. Specifically, the automatic adjustment arm has the following advantages:
1. Ensure constant clearance: Using an automatic adjustment arm can ensure that the vehicle maintains a constant braking clearance during driving, regardless of the degree of wear and tear, ensuring the best braking effect.  
2. Shorten braking response time: By reducing the consumption of compressed air, the automatic adjustment arm can achieve shorter braking response time, which is very important for improving the safety performance of vehicles.  
3. Easy installation: Compared to manual adjustment arms, automatic adjustment arms have lower installation difficulty, which is also their advantage.  
4. Brake balance effect: Especially with an increase in the number of axles, the automatic adjustment arm can exert a more prominent brake balance effect.
