Precautions for using the automatic adjusting arm
The automatic adjustment arm is designed to preset different brake clearance values according to different axle models. In normal use, if the gap exceeds the limit, the brake adjustment arm will drive the internal one-way clutch mechanism to reduce the gap value by one gear when the braking action is completed, so that the brake gap can be kept in a correct range.
