What This Brake Kit Helps Address

• Rear brake noise during stops
• Brake dust buildup on wheels
• Rust on exposed rotor surfaces
• Uneven or inconsistent braking feel
• Longer bed-in time after brake service

Installation Notes and Tips

Rear brake replacement should be performed on the axle specified in the fitment data only. The rotors arrive dry and ready for installation, which helps reduce prep time during service. Before installation, verify hub dimensions and configuration notes such as 2 wheel steering, heavy-duty brake pad set requirements, or 4.63 inch hub hole applications where listed. For best results, clean the hub mounting surface and follow proper torque and bedding procedures after installation.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE-style specifications using G3000/G11H18 cast iron, then inspected for balance and critical dimensions. Every rotor set is covered by a 12-month warranty against defects in material and workmanship.
