Dynamite Friction 4512-63200 Disc Brake Kit - Rear

Rear Brake Kit for Mercedes-Benz GLA250 and INFINITI QX30

The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit, part number 4512-63200, is a rear disc brake service kit built for specific Mercedes-Benz and INFINITI applications. It combines coated rotors, ceramic pads, and matching hardware in one package for a complete rear brake service.

Compatible With 2015-2020 Mercedes-Benz GLA250 rear and 2017-2019 INFINITI QX30 rear, including standard front disc and perforated front disc configurations. The DFC 4512-63200 is designed for drivers replacing worn rear brake components on these vehicles.

Key Features

• Rear disc brake kit with rotors, pads, and hardware
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads for reduced initial break-in time
• Rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Non-directional rotor finish for smoother pad bedding and quieter stops
• OE-style rotor machining and inspection for dimensional consistency

Product Details

DFC GEOSPEC rotors are processed dry and ready to install, which eliminates the need to clean oil-coated surfaces before assembly. The rotor casting uses G3000/G11H18 cast iron specifications and is machined to tight tolerances, then finished with a non-directional surface to support even pad contact. The coated surface helps resist rust better than conventional paint or zinc finishes. The 5000 Advanced pads are formulated for stable friction performance and are assembled with premium shims to help reduce brake noise and vibration. Part number 4512-63200 is a practical rear brake solution for Mercedes-Benz GLA250 and INFINITI QX30 owners seeking a matched rotor-and-pad service kit.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake noise during stops
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from fatigued hardware
• Reduced braking smoothness from worn rotors
• Longer brake service time caused by separate component sourcing

Installation Notes

Use this kit for rear brake service only. Verify rotor size, caliper condition, and vehicle configuration before installation, especially on INFINITI QX30 models with standard front disc or perforated front disc notes. Clean mating surfaces thoroughly, inspect caliper slides and mounting points, and follow the vehicle manufacturer’s torque specifications and bedding procedure after installation.

Quality Assurance

Each DFC GEOSPEC rotor is 100% inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when required. DFC states that every rotor is covered by a 12-month warranty against defects in material and workmanship.
