This locking pin is an original part from the manufacturer, designed for the brake system of the host tractor. It functions as a mechanical fastener that secures a linkage or lever within the brake assembly, ensuring the system applies and releases force predictably. A worn or incorrect pin introduces clearance that can cause delayed brake engagement or uneven pedal feel. The pin is machined to the same diameter and length as the original component, which maintains the correct fit in the clevis or bracket without requiring shimming. On installation, verify the pin is fully seated and that the retaining clip or cotter is properly engaged.
