Product Details

DFC Geospec Rotors with 5000 Advanced Brake Pads includes Hardware is designed around the demands of modern braking systems. The pads are post cured for stable friction performance and scorched to help reduce the need for extended break-in. The rotors use G3000/G11H18 cast iron and are machined to tight tolerances, then finished with a non-directional surface to support even pad contact and quieter stops. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging avoids the need to clean oil from the rotor before installation. Part number 4512-46155 is a practical choice for front brake service on the Cadillac XT4 and Buick Envision.

What This Brake Kit Helps Address

• Front brake wear on the Buick Envision or Cadillac XT4
• Rotor rust and surface corrosion
• Brake noise from worn hardware or fatigued clips
• Uneven pad bedding after rotor replacement
• Reduced pedal confidence from worn friction components
