What is the function of the brake adjustment arm

The function of the brake adjustment arm is to drive the camshaft to adjust the gap between the brake pad and the brake hub to the initial state. Therefore, the adjustment arm is a very important component in the braking system. The adjustment arm mainly includes the shell, vortex rod shaft, and turbine, which cooperate with each other to limit, but ultimately mainly to fix the vortex rod shaft limit, otherwise there will be displacement phenomenon during the braking process and unsafe factors.
The manual brake adjustment arm of a car is a security component, and its maintenance and adjustment are crucial to ensuring the safety of the car's braking. Otherwise, it may directly lead to brake failure and safety accidents. Below is a brief introduction to the adjustment arm:
1. Function: The adjusting arm is a safety device to adjust the brake clearance and connect the brake mechanism.
2. Adjustment method: For an adjustment arm with a locking sleeve structure, the locking sleeve should be pressed into the housing during adjustment, and then the worm shaft should be rotated to the right to adjust to the desired position (slowly rotate the worm shaft, and the locking sleeve should return to lock the worm shaft).
3. Precautions:
(1) During the use of the adjustment arm, regular maintenance and injection of butter from the oil nozzle are required;
(2) When the locking sleeve does not return during adjustment, metal should not be used to strike the locking sleeve or worm shaft parts;
(3) The position of the locking sleeve is equipped with a dust cover, and after adjustment, the dust cover must be properly covered to prevent rust.
