Rear Brake Kit for Mercedes-Benz S-Class

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit is built for rear brake service on select Mercedes-Benz S-Class applications. Part number 4512-63243 combines coated rotors, ceramic pads, and brake hardware in one service kit for a cleaner, OE-style brake refresh.

Key Features

• Rear disc brake kit for select Mercedes-Benz S450, S550, S560, and S400 applications
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed rotors that are ready to install without oil removal
• G3000/G11H18 cast iron rotor construction for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• DFC 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads to reduce initial break-in time and improve first-stop response
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Hardware kit engineered with PTFE coating, vulcanized rubber, and stainless steel

Product Line Details

DFC GEOSPEC Coated Rotors are designed to resist rust better than conventional painted or zinc-coated rotors and are machined to tight tolerances for consistent fit and finish. The 5000 Advanced Brake Pads are formulated for stable friction performance and are assembled with NVH-focused shims to support quieter operation in everyday driving.

Detailed Description

Part number 4512-63243 is a rear brake service kit for 2015 Mercedes-Benz S400, 2017 Mercedes-Benz S550, 2018-2020 Mercedes-Benz S450, and 2018-2021 Mercedes-Benz S560. It is not compatible with AMG Sport Package vehicles, and the 2017 S550 application is for vehicles without the Sport Package. This kit is a practical choice for Mercedes-Benz S560 rear brake replacement, Mercedes-Benz S450 rear brake service, and Mercedes-Benz S400 rear rotor and pad replacement when you want matched components in one package.

The rotors are processed dry and shipped dry, which eliminates the need to clean off oil before installation. Each rotor is finished with a non-directional surface to support more even pad contact, quieter stops, and a smoother bed-in process. The brake pads are post-cured and scorched to help deliver stable friction from the first stop, while the included hardware is designed to address wear, fatigue, and corrosion that can affect caliper movement and braking feel over time.

Common Issues This Kit Can Address

• Brake noise during stops
• Uneven pad wear from fatigued or corroded hardware
• Rust buildup on exposed rotor surfaces
• Longer pedal feel changes caused by worn brake components
• Reduced braking consistency from aged rear rotors and pads

Installation Notes and Tips

Confirm rear axle fitment before ordering, especially on Mercedes-Benz S450, S560, S550, and S400 models with package-specific brake configurations. Inspect caliper slides, mounting points, and hub surfaces during service, and follow proper bedding procedures after installation to help the pads and rotors seat evenly. Part number 4512-63243 is intended for rear brake service only.

Quality Assurance

DFC rotors are 100% inspected for critical dimensions and balance, with vented rotors corrected as needed during electronic mill-balancing. Each rotor is backed by a 12-month warranty against defects in material and workmanship.
