DFC GEOSPEC Rotor and Pad Line

The DFC GEOSPEC rotor line is machined to tight tolerances and processed dry, so the rotors are ready to install without oil removal or extra prep. The coated surface is designed to resist rust better than conventional paint or zinc finishes, while the non-directional finish supports quieter operation and more even pad seating. The 5000 Advanced pads are post cured, scorched to reduce initial break-in, and paired with premium rubber-steel-rubber shims for improved noise, vibration, and harshness control. Part number 4512-46086 brings these components together for rear brake service on Cadillac STS and CTS models.

Installation Notes

Confirm rear axle fitment, wheel configuration, and brake package before installation. Clean the hub mounting surface, inspect caliper slides, and replace worn hardware during service to help maintain proper caliper movement and pad contact. The coated rotor surface is processed dry and is ready for installation; the coating is removed naturally by the brake pads during use.
