The primary function of the adjusting arm is to precisely modulate the brake clearance. As trailers frequently engage their brakes during utilization, this repeated action can lead to
various degrees of increased clearance between the brake hub and the shoes. Such changes can result in braking delays and diminished braking efficacy. To combat these issues,
and ensure optimal vehicle safety, it is imperative to adjust the brake clearance. This adjustment helps in regulating and controlling the overall braking
functionality and sensitivity, ensuring a seamless and secure driving experience.
