Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered to match OEM specifications for fit, durability, and braking consistency. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging saves prep time during installation. The included DFC 5000 Advanced pads are post-cured for stable friction performance and scorched to reduce initial break-in effort, with shims added to improve noise, vibration, and harshness control. This part number 4504-45021 is a practical OE-style brake service solution for drivers maintaining braking performance on the Buick Regal Sportback, Chevrolet Equinox, GMC Terrain, Buick LaCrosse, and Chevrolet Malibu.

What This Brake Kit Helps Address

• Brake pulsation from worn or uneven rotors
• Reduced stopping performance from worn pads
• Rust buildup on exposed rotor surfaces
• Brake noise and vibration during everyday driving
• Extended service time caused by rotor prep and cleaning
