Front Brake Kit for INFINITI QX50 and QX55

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a front disc brake service kit built for select INFINITI applications. It combines coated rotors and advanced friction pads in one package for a direct brake service on the front axle.

Part number 4502-68029 is listed for 2019-2020 INFINITI QX50 front, 2021-2022 INFINITI QX50 front, and 2022 INFINITI QX55 front.

Key Features

• DFC GEOSPEC coated brake rotors with a silver-gray corrosion-resistant finish
• Rotors are processed dry and ready to install without oil removal
• G3000/G11H18 cast iron construction for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 100% inspected rotors with balance correction on vented designs
• DFC 5000 Advanced brake pads with post-cured friction material
• Scorched pads to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control

Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a complete front brake solution for drivers who need rotor and pad replacement in one service. The coated rotors help resist rust better than conventional paint or zinc finishes, while the dry packaging and ready-to-install surface can reduce prep time during brake work. The pads are formulated for stable friction performance and are assembled with shims to support quieter operation.

This part number, 4502-68029, is a fitment-based front brake kit for the INFINITI QX50 and INFINITI QX55. It is a practical choice for front brake service when replacing worn rotors and pads together.

Common Problems This Kit Can Address

• Front brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or rotor surface wear
• Reduced stopping performance from thin or heat-affected components
• Rust buildup on exposed rotor surfaces
• Extended brake service time when rotors and pads are replaced separately

Installation Notes and Tips

Compatible With 2019-2020 INFINITI QX50, front; 2021-2022 INFINITI QX50, front; and 2022 INFINITI QX55, front. Verify rotor size and front axle application before installation. Clean all mating surfaces, follow proper torque procedures, and complete a correct pad bed-in after installation for consistent braking performance.

Quality Assurance

DFC machines these rotors to tight tolerances, applies a non-directional finish, and inspects critical dimensions to OE specifications. Vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship.
