Product Details

DFC’s GEOSPEC rotor line is engineered to match OEM specifications for fit, durability, and balance. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance before release. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging saves prep time during installation. The 5000 Advanced ceramic pads are formulated for stable friction performance and consistent pedal feel across a wide range of driving conditions.

This part number 4512-45034 is a strong match for front brake service on vehicles such as the 1990 Chevrolet Lumina APV, 1990 Oldsmobile Silhouette, and 1990 Pontiac Trans Sport, along with earlier Buick Century, Chevrolet Celebrity, Oldsmobile Cutlass Ciera, and Pontiac 6000 front applications.

What It Helps Address

• Brake noise from worn or fatigued hardware
