Dynamite Friction 4512-63203 Disc Brake Kit - Rear

Rear Brake Kit for Mercedes-Benz S-Class

DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware, part number 4512-63203, is a rear disc brake kit built for select Mercedes-Benz S-Class applications. It combines coated rotors, ceramic pads, and matching hardware for a complete rear brake service on vehicles such as the Mercedes-Benz S560, S450, S550, S550e, S400, and Maybach S560.

Part number 4512-63203 is engineered for drivers who want OE-style fitment, corrosion protection, and consistent braking performance in one package.

Key Features

• Rear disc brake kit with rotors, ceramic brake pads, and hardware
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-to-install rotor coating reduces prep time during brake service
• Non-directional rotor finish supports even pad bed-in and quieter stops
• 5000 Advanced Brake Pads are post-cured and scorched for stable friction
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Hardware uses PTFE coating, vulcanized rubber, and stainless steel construction

Product Details

The DFC GEOSPEC rotor design uses G3000/G11H18 cast iron and is machined to tight tolerances for durability and OE-style stability. Each vented rotor is balance-checked and inspected for critical dimensions before release. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging means no oil film needs to be removed before installation. The 5000 Advanced ceramic pads are formulated for consistent friction and reduced break-in effort, making this kit a practical choice for rear brake service on Mercedes-Benz S560, S450, and S550 applications.

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

Common Reasons for Replacement

• Rear brake noise, squeal, or vibration
• Rust or corrosion on the rotor surface
• Uneven pad wear or reduced braking consistency
• Brake pulsation from worn or out-of-spec rotors
• Fatigued or corroded brake hardware
