The axle adjustment arm is a key component in the automotive braking system, whose main function is to adjust the brake clearance of the brake, ensuring that the clearance between the brake friction components (such as the brake hub and brake shoes) is maintained within an appropriate range.
Frequent braking during the use of a car can lead to continuous wear and tear of brake components, which increases the gap between the brake hub and the brake shoes, resulting in extended pedal travel, decreased brake chamber thrust, brake lag, and reduced braking force. In order to ensure the safety of vehicle driving, maintain the relative stability of pedal travel, and balance the operation of various brakes, it is necessary to adjust the brake clearance, and at this time, the adjustment arm plays a crucial role.
According to the adjustment method, the adjustment arm can be divided into two types: manual and automatic. Manual adjustment of the arm requires the driver to manually adjust the brake clearance based on the increase in brake wear and clearance after driving a certain distance of the vehicle to ensure the appropriate brake clearance. The automatic adjustment arm can automatically ensure that each wheel has a constant and consistent braking clearance, making the braking of the entire vehicle more sensitive, balanced, and effective, shortening the braking distance. Even if the brake shoe thickness and wear degree of each wheel are different, it can still ensure the best braking efficiency.
