The Meritor R509409 is a brake minor repair kit designed for heavy-duty truck brake systems. Decoded from the Meritor part-naming convention, "Kit Bk Rep Mnr" identifies this as a brake (Bk) repair (Rep) minor (Mnr) kit, meaning it contains the smaller hardware components typically needed for a brake service or partial rebuild rather than a full overhaul. No additional specifications, application data, or kit contents are listed in the available product data. For confirmation that R509409 is the correct part for your axle model and brake configuration, contact Pro Gear and Transmission directly before ordering.
