ACDelco Professional Reman Friction Ready Disc Brake Calipers use both aluminum and iron castings, making them the ideal high quality aftermarket replacement for many vehicles on the road today. These loaded calipers contain Ethylene Propylene (EPDM) rubber components to provide superior resistance to heat, corrosion, and leakage. Remanufacturing disc brake calipers is an automotive industry practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are 100% end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing also benefits the environment by returning components back into service rather than processing as scrap or simply disposing of them. ACDelco Professional Reman Friction Ready Disc Brake Calipers are developed without attached brake pads, allowing customization for the application at hand. Bleeder screws, copper sealing washers, hardware, and mounting brackets are all included for easy installation. These premium aftermarket replacement reman friction ready disc brake calipers are manufactured to meet or exceed your expectations for fit, form, and function.
