Product Details

DFC designed this brake service kit for vehicles that need OE-style fit, stable braking performance, and corrosion protection in the rear axle. The rotors are cast to G3000/G11H18 specifications, machined to tight tolerances, and inspected for balance and critical dimensions. The pads are formulated for consistent friction and reduced NVH, while the hardware addresses worn or corroded brake clips and contact points that can contribute to uneven wear and noise. Part number 4512-48114 is a practical choice for rear brake maintenance on Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and related applications.

Common Problems This Kit Can Address

• Rear brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor surfaces
• Uneven braking feel caused by worn rear brake components
• Longer stopping distances from depleted friction material
• Vibration or harshness during rear brake application
