Product Details

DFC Complete Brake Kits are organized to simplify brake service by pairing the correct rotors, pads, and hardware for the axle being serviced. This rear kit uses DFC GEOSPEC coated rotors, which are processed dry and ready to install, helping reduce prep time during brake replacement. The rotor casting is made to G3000/G11H18 cast iron specifications and finished with a non-directional surface to support even pad contact.

The 5000 Advanced ceramic pads are post cured for stable friction performance and scorched to reduce the need for extended break-in. DFC also uses premium shims to help control brake noise and vibration. The hardware kit is built with PTFE coating, vulcanized rubber, and stainless steel for OE-style form and function. This part number 4512-46153 is a direct rear brake service solution for 2019-2026 Cadillac XT4 and 2021-2026 Buick Envision rear brake applications listed below.
