Product Details

DFC’s GEOSPEC rotor line is engineered to match OE specifications for fit, durability, and braking stability. Each rotor is machined to tight tolerances, inspected for critical dimensions, and balanced where required to help deliver quieter, smoother stops. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging saves time during brake service.

The 5000 Advanced ceramic pads are formulated for consistent friction performance and are assembled with NVH-focused shims to help reduce brake noise and pedal harshness. The included hardware kit addresses a commonly overlooked wear item in brake service, helping restore proper caliper movement and spring tension on the rear axle. Part number 4512-45042 is a practical choice for a rear brake refresh on Cadillac DeVille, Buick Park Avenue, and Pontiac Bonneville models.

Common Brake Issues This Kit Can Address

• Rear brake noise from worn hardware or pad movement
• Uneven pad wear caused by fatigued or corroded hardware
• Rust buildup on exposed rotor surfaces
• Longer stopping distances from worn rear brake components
• Brake vibration or rough pedal feel from rotor wear

Installation Notes and Tips

Verify rear axle fitment by year, model, and VIN notes before ordering. This kit is for rear brake service only and includes components matched to the listed applications. Clean the hub face before rotor installation, follow proper torque specifications, and complete a full brake bed-in procedure after installation. Part number 4512-45042 should be matched to the exact vehicle notes, including the 2005 Cadillac DeVille VIN split and the heavy-duty exclusion.

Quality Assurance

DFC states that each rotor undergoes machining and 100% inspection of critical attributes to meet OE specifications. The rotors include a 12-month warranty against defects in material and workmanship.
