It connects the brake chamber pushrod to the camshaft, converting linear motion to rotational force that applies the brakes. The straight arm has two mounting hole positions (5-inch and 6-inch center distance) to fit different axle configurations. Regular manual adjustment maintains proper brake stroke and even pad wear, and replacement is typically needed when the adjuster is worn, seized, or the splines are damaged.
